Thermoplastic bitesize
WebbThermoplastic polyolefins (TPO) are raw materials obtained by the mixing of uncrosslinked amorphous rubbers and semi-crystalline polyolefin thermoplastics in a molten state. Most commercial TPOs are physical mixtures of EPRs and PPs that do not contain double bonds. Production processes do not include a vulcanization step.
