Typical Properties

Description 

SILASTIC™ RBL-9200-70 Liquid Silicone Rubber is a general purpose injection-molding elastomer. It belongs to the SILASTIC™ RBL-9200 Series, developed to be suitable for a wide range of typical silicone rubber applications.

How to Use 

港澳朱雀网Mixing and De-airing ：The A and B components are supplied strained and de-aired to be used as lot matched kits. Mix parts A and B in a 1:1 ratio. Meter mix equipment which pumps, meters and mixes the two components without incorporation of air is strongly recommended for production. If air bubbles are entrapped during mixing the mixture must be thoroughly de-gassed under vacuum. 

Pot Life ：When Parts A and B are mixed the mixture will remain useable for 72 hours at 25°C (77°F). 

Cleaning ：The uncured silicone can readily be removed by most hydrocarbon solvents. Polar solvents, such as ketones and alcohols are not suitable. 

Curing ：SILASTIC™ RBL-9200-70 Liquid Silicone Rubber cures readily at elevated temperatures. A 2 mm cross-section typically requires 6–10 seconds at 196°C (385°F). The cure time depends on the thickness and the cure temperature used. Cure can be inhibited by contact with certain materials such as amines, sulfur, and organotin complexes. 

港澳朱雀网Pigmentation ：This is normally carried out during mixing and dispensing of the two components. XIAMETER™ Color Master Batches are recommended with normal addition levels of 2 to 4% based on total volume.

港澳朱雀网Regulatory Compliance
