Hostaform® LGC90-QX
乙缩醛(POM)共聚物

Ticona

产品说明

Preliminary Data Sheet

Hostaform® LGC90-QX acetal copolymer is a specialty long fiber glass coupled grade formulated to provide exceptional mechanical properties while retaining other properties typical of acetal copolymers such as inherent lubricity and chemical resistance.

LGC90-QX is supplied in pellet form and is suitable for injection, injection-compression, extrusion, and extrusion-compression processes. For important additional process or equipment recommendations, please reference www.ticona.com/tech/processing under Celstran LFRT and Compel LFRT, or call the Ticona product hotline to request further information.

注射说明    

Long Fiber Reinforced Thermoplastic products may be processed using current standard injection molding machines having screw diameters greater than 40mm (1.6 inches).

A three-zone screw should be used, having a feed zone of approximately ten diameters, a compression zone of six, and a metering zone of four diameters. It should have an L/D ratio of 20:1 with a compression ratio of about 2:1. Screw flight depth should be at least 4.5mm (0.18 inches).

Wear and corrosion protective measures are recommended. Use interior armouring or a bimetallic coating on the cylinder and arm parts of the non-return valve with powdered metal steels. Additional corrosion protection of the melt carrying components in the plastication unit is recommended when working with Celstran LFRT nylon or PPS products.

Due to the short residence time, suitable shot volumes are from 30% to 70 % of the maximum metering capacity of the machine.

LFRT is usually processed using a free flow nozzle, but it requires an orifice diameter greater than 0.16 inches (4 mm) and preferably larger than 0.125 inches (6 mm). A shut-off nozzle may be advisable if a large orifice is used. An easy flowing, three-part, check-ring type of non-return valve with a large cross section is recommended.
