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.

To attain the very attractive properties of Spectrum PP, as regards the technical aspects, you need to follow the basic storage rules for such materials (in a dry and dark place with humidity below 15%). To obtain the best parameters of the printed object possible, it is recommended to dry the material prior to work.
