GF grades require higher injection pressures. Strongly anisotropic shrinkage (perpendicular to fibres > along axis). Increased nozzle and mould wear — nitrided steels recommended. Drying identical to base grade.
HDPE (code 2, LDPE code 4) is one of the most recycled plastics globally. Well-established collection streams. Mechanical recycling is common. The value of recycled material is significant.
PE is one of the most approved materials for food contact (FDA, EU regulation, EFSA). Widely used in food packaging, drinking water pipes (HDPE PE 100), and bottles. Excellent chemical inertness for all types of food.
