Abstract
A friction transmission belt has a rubber layer forming a pulley contacting portion. The rubber layer is made of a rubber composition containing a crosslinked rubber component and crosslinked polyolefin particles. Examples of the crosslinked polyolefin particles can contain ultrahigh molecular weight polyolefin particles having an average molecular weight of 500,000 or more.
Claims13
A friction transmission belt comprising a rubber layer forming a pulley contacting portion, wherein
- the rubber layer is made by crosslinking an uncrosslinked rubber composition comprising an uncrosslinked rubber component and radiation-crosslinked polyolefin particles.
A friction transmission belt comprising a rubber layer forming a pulley contacting portion, wherein
- the rubber layer is made of a rubber composition containing a crosslinked rubber component and crosslinked polyolefin particles, and
- the crosslinked polyolefin particles contain crosslinked polyolefin hollow particles having hollow portions.
A friction transmission belt comprising a rubber layer forming a pulley contacting portion, wherein
- the rubber layer is made of a rubber composition containing a crosslinked rubber component and crosslinked polyolefin particles prepared by irradiating uncrosslinked polyolefin particles with radiation.
