Toughened
A toughening system for low-temperature and high-speed impact, offered in three grades by flow and wall thickness.
01 Material Overview
POK already outperforms most engineering plastics on impact, but low temperatures, high-speed impact or thick walls with stress concentrations still call for an additional toughening system.
JH960STP is the general toughening grade for most impact-resistant housings; JH906ST5 is the low-flow version for thick-wall parts, reducing internal voids and stress concentration; JH900ST2 is the high-flow version for thin-wall parts that must resist impact, such as protective gear and case shells.
Toughening brings a slight loss of stiffness and heat resistance — a classic trade-off. Where an article needs both high stiffness and high impact, consider a combined glass fibre plus toughener system, which requires separate development.
