Addisil™ 442 E

About
The Addisil 4X2 E series is a two-component heat curable rubber for making elastomers (HCE) with a hardness range between 40 and 80 Shore A for medical applications. This series is based on a platinum cure system, which is particularly suitable for high value extrusion applications where regulatory compliance, transparency, mechanical performance and/or productivity are important. The series is especially suitable for the manufacture of extruded transparent tubing and profiles for use in healthcare applications. Key Features and Benefits- High transparency, no yellowing Excellent mechanical properties Dry, non-stick surface Odourless during processing and in its application Fast curing Long shelf-life of 6 months for the single component if stored appropriately Very long pot life of 2 to 4 weeks for the mixed components&&
