Plasticiser, also known as plasticiser, is a kind of polymer material additive. Adding plasticisers to plastic products can increase the flexibility, extensibility and plasticity of plastics, reduce the flow temperature and hardness of plastics, which is conducive to the moulding of plastic products.
Application Fields
PVC products: wires and cables, flooring, artificial leather, hoses, etc. (plasticisers can account for up to 30%-50%).
Medical supplies: blood bags, infusion tubes (need to use non-toxic plasticisers such as DEHP alternatives).
Food packaging: cling film, bottle cap liners (need to meet food-grade standards).
Toys and children’s products: strict restrictions on phthalates in the EU and other regions.
Coatings & Adhesives: Improve flexibility and adhesion of coatings.
Lower Tg: Keeps the material soft at lower temperatures.
Improve processability: Reduces melt viscosity, facilitating injection moulding, extrusion and other processes.
Narrowly speaking, the stabilizer mainly refers to the polymer plastics, rubber, synthetic fibres to maintain stability, to prevent its decomposition, aging reagents.
