Silicone Rubber – An Outline

Nitrile and polyacrylic supplies have temperature ranges of −34°C to 107°C and −34°C to 177°C, respectively. Both require steady lubrication.

silicone rubber (read this) is just not really useful to be used with scorching natural materials. If, for specific causes, its use is contemplated, the producer should be consulted regarding its potential use for a specific utility.

Neoprene, a effectively-proved packing material, has a temperature range of −60°C to 107°C however as a result of it is unsuitable for use with many organic liquids it is generally used only with aqueous solutions. It possesses good resistance to abrasion, which makes it particularly useful with slurries or the place there’s abrasive contamination.

Metallic packings of aluminium, silicone rubber copper and lead cover a really large temperature vary up to 540°C. They should be matched to the shaft material, since shaft finish and tolerance are crucial components in total efficiency. The good limiting consider using metallic packings is the issue of guaranteeing corrosion resistance with all the probably process materials.

The textile fibres have a limited range of software. They may be used with scorching or chilly water, steam, oils and ammonia up to a maximum temperature of 100° C. Asbestos fibre is more versatile, might be be used as compression packing materials with sizzling water, super-heated steam, silicone rubber hot oils and gases up to 310°C.
