KEY FEATURES
- 100 % Silicone-Free compound — formulated without PDMS or any silicone-based additives.
- Excellent flexibility and compression recovery, even under continuous heat and pressure.
- Heat-resistant up to +160 °C (EPDM) and +260 °C (FKM / Viton®).
- Superior resistance to vacuum pressure and a wide range of chemicals.
- Ultra-low outgassing, ideal for vacuum lamination and cleanroom environments.
- Fully customizable hardness, thickness, and dimensions to meet specific customer requirements.
PRODUCT DESCRIPTION
In high-purity manufacturing industries such as electronics, semiconductor, cleanroom production, and HDD assembly,
even trace levels of silicone contamination can cause critical failures — including delamination, outgassing, and reduced layer adhesion.
Polytech Industry Company Limited is a trusted manufacturer of custom Silicone-Free Rubber products,
specifically developed for contamination-free environments that require molecular-level cleanliness and reliable performance.
We offer two production formats:
- Silicone-Free Rubber Sheets
- Silicone-Free Molded Parts
All products are made using high-purity compounds completely free from PDMS (Polydimethylsiloxane) and any volatile silicone components,
ensuring zero contamination during vacuum lamination, PCB manufacturing, and cleanroom assembly processes.
AVAILABLE MATERIALS
- EPDM (Ethylene Propylene Diene Monomer) : Excellent resistance to heat, ozone, and chemicals — ideal for cleanroom environments.
- FKM / Viton® (Fluoroelastomer) : Exceptional resistance to high temperature and concentrated chemicals — perfect for sealing systems in precision operations such as HDD and semiconductor processes.
