PVC door casings are widely used in home and engineering decoration, mostly produced by extrusion, with strict requirements for thermal stability, lubricity, surface quality and environmental protection. Jiabetter provides a full range of professional PVC additives including calcium‑zinc stabilizers, PE wax, EBS and foaming microspheres, which perfectly match the whole production process of PVC door casings.

Our eco‑friendly calcium‑zinc stabilizers effectively prevent PVC from thermal degradation, yellowing and scorching during high‑temperature extrusion. They keep stable color of finished door casings, suit high‑calcium‑filled formulas and greatly reduce defective products.

Jiabetter PE wax and EBS act as internal and external lubricants. They improve melt fluidity, avoid mold sticking and blooming, speed up extrusion, deliver smooth surface and neat edges, and raise production efficiency.

For lightweight foamed door casings, Jiabetter foaming microspheres create uniform micro‑foam structure. They reduce product weight and raw material cost, improve sound insulation and impact resistance, making door casings tough and deformation‑resistant.

All Jiabetter additives are lead‑free, cadmium‑free and comply with RoHS & REACH standards, suitable for high‑end home decoration and export orders. With excellent compatibility, they have no negative impact on lamination, heat transfer printing and other post‑processing steps. Our one‑stop additive solution helps door casing manufacturers improve quality, cut costs and boost productivity.
