Two-Part Solid Silicone Rubber for Insulators

Model No.
SSR1501-35A/B,SSR1501-45A/B,SSR1501-50A/B

Product Description
The SR335 two-part solid silicone rubber is a platinum catalyzed bi-component solid silicone rubber. It is suitable for extrusion or injection molding in cold shrink tubing. Our two-part solid silicone rubber features good aging resistance, high tear resistance, superior dielectric property, high tensile stretch, etc. It is non-reactive, stable and resistant to extreme environments and temperatures from -60℃ to 250℃ while still maintaining its useful properties. Due to these properties, our solid silicone rubber is used to cold shrink cable accessories, lightning arresters, medium to high voltage insulation materials, etc.

Storage
Keep sealed and store in cool, dry and dark place. It has a shelf life of 12 months.

Usage
Use a static mixer to mix the two components, A and B with a ratio of 1:1. Feed the mixture directly into an injection molding machine. Note: the mixture has an effective operating time of 48 hours.

Packing
Our two-part solid silicone rubber is packed in 20kg barrels.

Model No.
SR6680/SR6681

Product Description
The SR6680 solid silicone rubber is a peroxide vulcanized solid silicone rubber which is particularly suitable for extrusion or compression molding in cold shrink cable accessories. This two-part solid silicone rubber features good aging resistance, high tear resistance, superior dielectric property, high tensile stretch, etc. It is non-reactive, stable and resistant to extreme environments and temperatures form -60℃ to 250℃ while still maintaining its useful properties. Due to these properties, our solid silicone rubber is used to cold shrink cable accessories, lightning arresters, medium to high voltage insulation materials, etc.

Storage
Keep sealed and store in cool, dry and dark place. It has a shelf life of 12 months.

Usage
Evenly mix this silicone rubber with a peroxide catalyst at an appropriate ratio and then feed the mixture directly into the molding machine.

Packing
Our two-part solid silicone rubber is packed in 20kg PE cartons.
