Einar® mould release solutions for polypropylene (PP) Einar® 201 for mould release applications Einar® 201 is a very reliable general purpose mould release for PP injection moulding applications. The product can be dosed at an optimum concentration in both homopolymers, random and impact copolymers and will secure efficient release of moulded parts. Einar® 201 has an ideal migration profile in PP that guarantees sufficient lubrication and will promote lower cycle times and continuous operation. Einar® 201 is also an efficient de-nesting additive and allows easy separation of stacked parts. Recommended loading levels for homopolymers are 0.2-0.4%, for random copolymers 0.1 - 0.2% and for impact copolymers 0.3 - 0.5%. Einar® 201 is available in both powder and pellet form providing options for better mixing with either powder or pelletized PP. The pellet form being preferred in many situations where a powder at elevated temperatures during mixing and feeding will be difficult to handle and transport in feeding and dosing equipment.
