PVC Additive-ACR

ACR is a kind of polymer with special structure. ACR resin is composed of methyl methacrylate (MMA), butyl acrylate by seed emulsion polymerization is a kind of thermoplastic graft polymer, and has a dual function of impact modification and processing of plastic additives, mainly used for hard and half hard PVC products, especially the chemical building materials, such as profiles, pipes, pipe fittings, sheet, foam materials, etc

Discription

ACR is a kind of polymer with special structure. ACR resin is composed of methyl methacrylate (MMA), butyl acrylate by seed emulsion polymerization is a kind of thermoplastic graft polymer, and has a dual function of impact modification and processing of plastic additives, mainly used for hard and half hard PVC products, especially the chemical building materials, such as profiles, pipes, pipe fittings, sheet, foam materials, etc

Characteristics of ACR

1.Improve the consistency of PVC products, such as luster, tensile strength, impact strength and elongation offracture.

2.Improve the rheological behavior of PVC thermo plastic state, improve the melt strength, avoid melt fracture, and improve the inner quality and surface luster of the products.

3. It has the stability of long forming process.

4. Significantly reduce the deposition of various additives, such as stabilizers and pigments, on the surface of processing machinery.

5. To promote the uniformity and refinement of foam holes in foaming products.

6. It can be well solubilized with PVC at the processing temperature, and promote uniform synchronous plasticization.

7. Maintain the original excellent performance of PVC, which can promote smooth processing in all kinds of processing machinery, and effectively improve the weather resistance.

8.It is effective to prevent the pressure fluctuation and flow scars produced by extrusion molding in the extrusion and injection process.

Applications of ACR

In the production process of PVC resin, should add 1% ~ 5% additives. ACR is most applied in extrusion, injection molding, blow molding, blister, and in the calendaring, etc. It can effectively control melt fracture, promote PVC gel plasticization and improve plasticizing quality. Although ACR has less addition in the formulation, the effect on the processing performance of PVC is relatively large.
