Glass Fibre Reinforced
15%–50% glass fibre reinforcement that lifts stiffness and heat deflection temperature — for high-load structural parts and connectors.
01 Material Overview
Glass fibre reinforcement is the largest volume system among modified POK grades. As glass content rises from 15% to 50%, flexural modulus and heat deflection temperature climb together while shrinkage falls and dimensional stability improves.
JH960G3 (GF15%) covers general structural parts and brackets; JH960G6 (GF30%) is the workhorse reinforced grade, balancing stiffness and toughness, widely used in connectors and housings; JH900G8 (GF40%) and JH900G10 (GF50%) target high-load and thin-wall high-stiffness applications, with G10 built on a high-flow base to improve filling over long flow paths.
Glass fibre systems are markedly anisotropic: shrinkage along the flow direction differs considerably from shrinkage across it. When designing the tool, apply the separate ranges given in the TDS and consider how gate position will affect fibre orientation.
