Welcome to Precision Polymer Engineering at SEMICON Korea!

Precision Polymer Engineering (PPE) manufactures innovative seals, O-rings, slit valve doors, wafer handling components and custom parts - delivering sealing solutions able to perform to the highest standards in aggressive semiconductor production environments.

Using the latest polymer technology, PPE seals are designed to provide excellent mechanical properties with extended high temperature performance, outstanding chemical and plasma resistance. Our ultra-pure organic elastomer grades do not contain carbon or metal fillers, reducing particle generation and minimising contamination. 

PPE will be showcasing its range of cost effective elastomer materials at SEMICON Korea 2019, with each of our material families engineered to reduce the cost of consumables by whilst maintaining excellent levels of sealing performance.

  • Perlast Helios G7HA is a perfluoroelastomer grade which has been specifically designed for high temperature applications in semiconductor processes.

    Perlast Helios G7HA offers outstanding performance over 300 Celsius, and has excellent overall plasma resistance - especially against high concentrations of fluorine radical plasmas. This grade ensures no trade-off between high temperature performance and high purity, with a fully organic formulation offering extremely ow trade metal levels for higher yields and reduced process contamination.

    Perlast Helios G7HA combines outstanding long term mechanical performance, excellent plasma resistance and ultra-high purity, which can help to significantly reduce operational downtime and cost of ownership.

BEWARE - Special Warning Notice about ExpoGuide and FAIRGuide

With the ongoing solicitations, SEMI would like to continue to alert you with questionable professional practices perpetrated against exhibitors by (Austria) and Expo Guide (Mexico), Event Fair - The Exhibitors' Guide with their misleading directory services. There may be others that we are not aware of and are hence not named here. 

These companies provide legitimate exhibition guides aimed at exhibitors across the globe offering online listing services. They use a form which resembles and organizer's free catalogue listing service, inviting exhibitors to complete the form for an entry in an on-line directory. Unsuspecting exhibitors who sign and return the form are then contracted into a three-year, non-retractable agreement, which could cost the exhibitor a significant amount of money, with very limited foreseeable benefits. The details are often available on the form itself, but are often too small and insignificant to be noticed. It is always wise to really the small print before signing a contract, and if the information is impossible to read then the contract should not be signed. These publications have no connection with SEMI or any of our events, and it is important that all companies are made aware of this. 

Should you receive any communication from the Expo-Guide and or related company, please IGNORE THEM COMPLETELY and DO NOT COMMUNICATE WITH THEM IN ANY WAY.
