High impact and chemical resistance

Spectrum PP is a new material based on a random unfilled copolymer polypropylene material. It has good mechanical properties combined with outstanding chemical resistance and low density. Our material does not require a heated building chamber to be printed and it exhibits enhanced layer bonding, thus reducing the anisotropy of the final part. A PP build plate is recommended for the neat material. Its specific quality is a low absorption of moisture, up to 0.3%.

In addition, PP features high flexibility (ultimate elongation - 500%) and high impact resistance plus reduced moment of inertia as compared to metal parts. PP has also a good chemical, temperature and electrical resistance. PP enables to obtain a relatively high resistance to thermal ageing, good tribological properties, including dry friction conditions such as in slide bearings. Very good mechanical properties of PP provide for a wide range of diverse applications.
