Another common material in which bushings are made is neoprene.

Rubber is made of latex, which comes from some plants and trees. While rubber is sensitive to heat, neoprene can withstand temperatures of up to degrees. Research shows that global sales We use cookies to improve your experience. By your continued use of this site you accept such use.
