PROPOLDER™ MPP2040 is a maleic anhydride modified polypropylene (PP) polymer in fine particle powder form. Unlike waxes, these higher molecular weight materials exhibit high toughness. PROPOLDER™ MPP Series materials are polypropylene powders with grafted polar groups for enhanced performance in specialty applications.

Polyethylene Microparticle Powder Summary
Pure High density polyethylene homopolymer polymer in finely sized rounded powder form.

Microparticles are fine particles between aproximately 0.1 and 150 micron (um) in size. Everyone encounters microparicles on a daily basis when exposed to substances found in the natural environment such as pollen, very fine sand, and dust. Visit the University of Utah learning center for an interesting illustration of size and scale found in nature. By comparison, an individual themrmoplastic microparticle as illustrated by the micro photographs below are generally to small to be seen by the naked eye. In large quantities, microparicles are often referred to as micropowders.

Because microparicles are so small in size, they have a large surface-to-volume ratio which can be of great benefit to industry. Aspect ratio, the ratio of its longer dimension to its shorter dimension, can also have a significant impact on application performance. Therefore, size and shape of microparicles are valued for the properties they provide. Plastic microparticles are most often used as a minor component in a formulary product for industry.

Primarily Microparicle Markets for finely sized thermoplastic powders include fiberglass reinforced plastics, cosmetics, inks and toners, paints and coatings, partitioning, textiles and many other industries.

FIPOLDER products are predominantly used as an additive or bonding agent in the manufacture of the following products:
Glass fiber reinforced plastics (SMC, BMC : low shrinkage agent, lubricant)
Plastic-elastomer blends (anti-adhesive)
Paints and varnishes
Dry cell batteries
Cosmetics
