PIB (POLYISOBUTYLENE)—Mid MW (Food Grade) PIB-MW(Food Grade)

  • Description

Product Description

Typical properties:

Transparent, yellowish, semi-solid, odorless, non-toxic.

Applications:

The physical harmlessness of polyisobutylene has been proved for many different applications

1. Chewing gum base. MM PIB provides the suppleness and elasticity to the chewing gum and has excellent capacity to intake fillers. MM PIB has a neutral taste and odor, which enables the flavors contained in the chewing gum to unfold their full taste.

2. Medical adhesive and Medical plaster.

3. Food wrapping medium.

4. Food packing hot melt adhesive.
