ForTii® XS81B

Name: ForTii® XS81B
Brand: ForTii®

ForTii® XS81B is a breakthrough high-temperature polyamide with halogen-free and halogen-containing flame retardant grades and a broad and versatile portfolio of grades that deliver high performance with a unique balance of properties. It is mainly used for demanding applications in the electronics, lighting, automotive, white goods, industrial, and aerospace industries. It has excellent impact resistance and high stiffness. Its good processing ability allows for high cosmetic requirements and good bonding in various painting processes. It is very suitable for mobile phone middle frame applications due to its low warpage and excellent performance in tumbling tests. It is 50% glass-reinforced, PA4T, and is best suited for injection molding.

Plastics and Elastomers Functions: Resin
Antenna Splitters Application Data: ForTii® XS81B allows for reliable solutions due to its excellent performance under high-temperature and chemical processing and due to its high strength and tenacity implying high resistance to constant pulling and falling of the phones. ForTii® XS81B allows for cost effective solutions due to its high flowability facilitating thus the insert molding process
Plastics and Elastomers Processing Methods: Injection Molding
Medium Voltage Circuit Breakers Application Data: ForTii® PA4T allows for more sustainable solutions in end-products due to lower CO₂ footprint as compared to solutions with epoxy Xlink agent. ForTii® PA4T allows for potential system cost reduction opportunities due to part integration possibilities , possible thinner wall design withlower profiles possibilities, reduced cycle times with lower production losses
