  • High performance plastic types
    There are many different types of high performance plastics available on the market. BKB Precision specialises in high performance plastics, such as PPS, PEI or PEEK....



    Polyetheretherketone, ohterwise known as PEEK, has a very high and long-lasting operating temperature (around 280º C). The plastic is stiff, strong and has extremely good tensile and flexural strength at varying loads. In addition, PEEK is resistant against energy-rich radiation and is self-extinguishing according to UL94. The application of PEEK is very diverse. It is use in semi-conduction, the medical industry, the aerospace industry, research etc. PEEK machining is a delicate procedure that BKB has mastered over the years. We are an expert when it comes to PEEK and know how to manage any requests regarding this high performance plastic. Feel free to contact us to learn more about PEEK machining.


    Polyimide, also known under its abbreviation PI, can be used at high (and extremely low) temperatures, has no visible melting point and thus retains good shape stability and mechanical properties. The upper threshold at short peak temperatures is 450°C. Polyimide also extinguishes flames, is electrically insulating, resists energy-rich radiation and has minimal outgassing in a vacuum. Thanks to its intrinsic purity, PI sheets and poles are frequently used in high purity applications, such as semi-conduction, the aerospace industry and primary research (CERN).


    PPS is a thermoplastic polymer with favourable properties, making it a suitable technical polymer for special applications. It is resistant against high temperatures of over 200 °C. It is a good electric insulator and is resistant against acids and alkalis and is almost insoluble in organic solvents under 200°C. PPS is also naturally flame retardant. In many cases, it can be used as an alternative for PEEK. Whether you prefer PPS or PEEK machining, BKB Precision is an excellent partner for working with both materials.

    Polyether Imide, otherwise known as PEI, belongs to the group of high performance plastics. It has good thermal and mechanical properties, is easily sterilised and has a high mechanical strength across a wide operation temperature. PEI-plastic extinguishes flames and has a low smoke development. This plastic has a good resistance against UV and chemicals and is suited for direct contact with foodstuffs. This high performance plastic is suited for application in the semi-conduction industry and is often used for aeroplane parts. 


    PAI, also called Polyamide Imide, has excellent mechanical properties. The plastic is used for machining parts that need to withstand a heavy load. PAI has wear resistance, a low frictional resistance and is resistant against gamma and X-ray radiation. PAI is used for electronic / electrically insulating parts and applications in the medical industry.

    Torlon® is a PAI type that combines excellent mechanic strength, stiffness and creep resistance across a wide range of temperatures. It has an extremely low expansion coefficient. Torlon® plastics are particularly suited for applications in high temperatures. BKB is your PAI machining specialist. From our machinery in the Netherlands, we take care of any and all PAI machining efforts.


    PTFE, Polytetrafluoroethylene, is a fluoride plastic. Its most prominent characteristic is its lowest friction coefficient of all solids and its highest resistance against chemicals. Its material purity also makes PTFE suited for direct contact with foodstuffs. Its fluoride atoms and properties make this plastic suitable for many areas. In heavy applications, it offers advantages regarding stable and improved functions. PTFE is also known as Teflon. The decrease in dimensional accuracy of this material during machining should be kept in mind.

  • Technical plastic types
    Technical or engineering plastics are often used for equipment construction, technical applications or other precision components. BKB Precision is your specialist in machining technical plastics like PC,PVC,PA,POM, PMMA and PETG....

  • PA (Polyamide)

    Polyamide, also called Nylon, is a very wear-resistant plastic. The material is hard, stiff, impact-resistant, and has reasonably good machining possibilities. PA has good mechanical properties and is mostly used in mechanical engineering. You can improve certain properties of PA by adding lubricant or glass. The drawback of PA is, among other things, its moisture susceptibility.

    POM (Polyoxymethylene Acetal Polymer)

    Polyoxymethylene Acetal Polymer, shortened as POM, is a strong and hard plastic with shape stability. The material has a low friction resistance and can be sterilized. In addition, POM has good elasticity and the plastic can absorb heavy impacts or shocks. POM can be mechanically machined perfectly and has a good chemical resistance. Special editions exist, including foodstuffs-appropriate plastics and material that is resistant against organic solvents. POM is mostly used in the foodstuffs industry and machine construction.

    PC (Polycarbonate)

    Polycarbonate, also known as PC, is a transparent plastic, suited for industrial engineering. This plastic lets through light, has a high impact resistance and is perfectly suited for gluing, shaping and welding. Polycarbonate is mostly used for medical devices and parts. The plastic is not standard UV-resistant and is liable to scratching. There are, however, editions that are UV resistant and that have an extra scratch-resistant coating. An ESD-safe coating on PC can also be supplied. BKB Precision has mastered Polycarbonate machining over the years. We use the latest technologies and highest quality standards when machining PC. Feel free to contact us for questions regarding Polycarbonate machining.

    HMPE (High Molecular Polyethylene)

    HMPE stands for High Molecular Polyethylene. The molecular density determines the properties of the material. HMPE is moisture-repellent and has good wear and impact-resistance. HMPE is very well-suited for mechanical plastic machining and is mostly used in the transport industry. Special HMPE editions are also exceptionally suitable for the food industry and machine construction. There are various HMPE qualities available, like HMPE500 and HMPE1000. At less than 500, it is also called HDPE or High Density Polyethylene.

    PMMA (Polymethyl Methacrylate)

    Polymethyl Methacrylate, also known as Acrylate, is a transparent and pure plastic and lets through more light than glass. The material also has good machining possibilities for high (optical) quality. PMMA is often used for constructive applications, for example for sight glasses and liquid measuring systems. It is also more UV-resistant than other transparent plastics. In addition, this plastic is also suited for foodstuffs. PMMA is available in various colours and light transmissions (opal), as well as in ESD-safe ‘Eslon’ material.

    PETG (Polyethylene terephthalateglycol)

    Polyethylene terephthalateglycol. This polyester plastic is the middle ground between PMMA and PC. It is crystal clear and has good vacuum shape properties. Its heat resistance is limited, as it is lower than that of PMMA and PC. PET-G is self-extinguishing and suited for direct contact with foodstuffs. A drawback is its susceptibility to scratches, just like PC.

    PVC (Polyvinyl Chloride) 

    Polyvinyl Chloride, shortened as PVC, has wear resistance and shape stability. It has a smooth and straight surface, excellent chemical resistance properties and is suited for gluing and welding. The material can be machined precisely. PVC has a good price/performance ratio and is often used in machine construction, the electro industry and in chemical equipment construction. The operating temperature of PVC is limited and it is not UV-resistant. It is available in multiple colours, including a transparent edition. BKB Precision is specialized in PVC machining. Our highly-trained and motivated employees are always willing to help you with questions regarding PVC machining.

    PETP (​Polyethylene Terephthalate) 

    Polyethylene Terephthalate has wear resistance and shape stability and is dimensionally accurate. This is why PETP is characterized as one of the hardest plastics in existence. It is a relatively brittle plastic and is mostly used in the foodstuffs industry. It serves as a substitute for POM in many cases.
