PPA 2200, Polymer Processing Additives

Lanpoly PPA 2200, containing 97% active ingredient, is a kind of free-flowing 25 mesh white or light yellow powder. It can improve the processing performance of polyolefin with very low additive amount (50-800 ppm), producing no influence on the physical properties of resins themselves or the bonding, printing and heat sealing properties of products.

Appearance

Free-flowing white or light yellow powder

Applications

Suitable for polyolefin resins such as mLLDPE, LLDPE, HDPE and EVA and used for the extrusion production of blown film, cast film, sheets, pipes, cable insulation materials and sheath materials.

Functions Improve film surface quality by eliminating melt fracture Decrease fisheye formation in extrusion Eliminate die build up, prolong producing time Increase LLDPE amount, improve quality and reduce cost Increase output without changing back pressure Physical properties Density: 0.7g/cm3
Particle size: ＜25 mesh Volatile (105℃, 1h): 0.15% Food contact safety

Lanpoly PPA meet the demands of FDA 21 CFR 177.1520 and can contact with food. Detailed information for request.

Processing guide

The dispersion degree of PPA in resins determines its effect to a great extent. 2-3% masterbatch is recommended to be first made by twin screw extruder and then added to extrusion resins according to target additive amount. In first-time use, there will be 60-90 min onset time according to equipment, raw material and shearing speed. For equipment that long-term continuously uses PPA 2200, there’s no onset time.

Package and maintenance 25KGS/CTN Shelf life: 1 year Storage below 30℃, keep away from light and humidity.
