Release agents for plastic moulding of polymers and technopolymers

In plastic moulding processes, using an inadequate release agent can cause several issues that affect part quality and production efficiency.

The most frequent problems include material adhesion to the mould, difficulty in part ejection, surface defects and accumulation of residues that compromise the quality of the moulded item.

These issues are particularly common in continuous or high-precision production cycles, where uniformity and process repeatability are required. Using release agents specifically designed for plastics improves demoulding, reduces waste and keeps mould surfaces clean.

In plastic moulding, one of the most common problems is the difficulty of part ejection from the mould, especially with complex surfaces or high-viscosity materials.

Material sticking to the mould can cause surface defects, deformations or part breakage, compromising final product quality. Residue build-up on mould surfaces also reduces precision and increases maintenance needs.

In continuous production cycles these problems translate into more waste, slowdowns and machine downtime. Using release agents specifically designed for plastics improves demoulding, reduces adhesion and keeps surfaces clean over time.

Advanced formulations also ensure consistent performance even under complex operating conditions.

In plastic moulding, silicone release agents are widely used for their release capability but can create limitations in downstream stages of the process.

Silicone residues can interfere with painting, bonding or surface treatments, reducing adhesion and compromising final product quality. For this reason, non-silicone release agents are preferred in technical applications.

These formulations deliver clean surfaces compatible with downstream processing while maintaining good release performance. They are particularly recommended in automotive, electronics and advanced industrial sectors where high quality standards are required.

The correct use of a release agent optimises the entire plastic moulding process, improving not only demoulding but also overall production efficiency.

Uniform, controlled application reduces friction between mould and material, improves surface quality and limits mould wear.

Using high-performance products also reduces application frequency and ensures consistent performance over time. Integration of the release agent into the production process should be evaluated based on material, mould geometry and operating conditions to deliver maximum quality and productivity.
