TAFMER™ A-4085S by Mitsui Chemicals is a specialty, ethylene-based a-olefin elastomer (TPO) grade. Provides high speed packing, low crystallinity, transparency, low glass transition temperature and low temperature impact resistance.
- Exhibits low melting point, low heat seal initiation temperature, low young's modulus, softness and flexibility.
- Shows low specific gravity, insolubility in water, elasticity, good filler containability, foamability and crosslinkability.
- Is miscible with polyethylene (PE) and compatible with polypropylene (PP) for adhesion strength control.
- TAFMER™ A-4085S is suitable for processing by blown film and coating extrusion.
- Used in blown PE sealant layers.
- Meets FDA title 21, parts 170 to 189, FCN (food contact notification), EU Directive 2002/72/EC and its amendment 2008/39/EC.
