Supply tough, dependable CVJ boots that keep grease in and trouble out

A good constant velocity joint (CVJ), or homokinetic joint, will perform as long as the boot that protects it.

With proven Silastic® brand silicone elastomers and custom compounding support from Dow Corning, you can fabricate CVJ boots that:

• Are grease resistant -- keep grease from leaking out
• Prevent damaging dirt, water, and road deicing salt from getting in
• Extend CV joint life and reduce maintenance

Silastic silicone elastomers:

• Have tough rubber capabilities
• Resist deformation at high-speed shaft revolutions
• Maintain their mechanical properties and grease resistance over a wide range of temperatures, from -40 to 200ºC (-40 to 392ºF) -- temperatures that would defeat organic elastomers.

This makes them the material of choice for CVJ boots, homokinetic joint boots, steering shaft joint covers, steering angle correction covers, and transmission applications.

Add long-life value and trouble-free performance Improve sealing performance   Manufacture CVJ boots that: Perform over a wide temperature range -- from summer heat to winter cold Give you greater flexibility in engine layout and design -- can be placed close to hot metal Maintain their flexibility and resiliency Last longer   Learn More Start with the right elastomer For CVJ boots, we recommend a high-consistency rubber (HCR) elastomer or a liquid silicone rubber (LSR) with a durometer between 50 and 70 Shore A and excellent physical properties, which can withstand temperatures as high as 232º C (450º F) and is able to be easily molded in compression, transfer, or injection molding machines.
