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.
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.
