Acrylic Impact Modifiers, with their distinctive core-shell structure and exceptional properties, it has better processability, impact resistance, beautiful surface and excellent aging resistance.can improve the impact resistance and promote the gel and plasticization of engineering plastics，Improve the toughness of PVC products. enhance the durability and aesthetic appeal of their PVC products.

MBS Impact Modifier, also known as MBS resin, is a copolymer comprising methyl methacrylate, butadiene, and styrene. Its compatibility with PVC is remarkable due to a solubility parameter ranging from 94 to 95, closely matching that of PVC.

Chlorinated Polyethylene, often referred to as CPE, is a polymer derived from High-Density Polyethylene (HDPE) through partial chlorination. The introduction of chlorine atoms grants CPE a degree of softness and rubber-like properties. Moreover, it transforms CPE into a polar polymer with polar groups akin to PVC, bolstering compatibility with PVC.

PVC internal lubricants are characterized by their strong compatibility with PVC polymers. By reducing cohesion between polymer molecules within the PVC matrix, internal lubricants effectively lower friction heat generation, promoting improved melt fluidity. This results in smoother processing of PVC materials.

PVC external lubricants limited compatibility with polymers, which allows them to migrate from the melt to the exterior. This migration forms a lubricating thin layer at the interface between the plastic melt and metal, effectively reducing friction. External lubricants play a crucial role in minimizing friction and improving the overall processing of PVC.

Acrylic Processing Aid or called ACR, It is a thermoplastic graft polymer born from the emulsion polymerization of methyl methacrylate and butyl acrylate. Characterized by its core-shell structure, ACR boasts a molecular weight typically ranging from 1 to 8 million (weight average molecular weight) and a density between 1.05 and 1.20 g/cm³.

SAN Processing Aid is a super high molecular weight polymer copolymerized from styrene and acrylonitrile,with a molecular weight exceeding 5 million that enhancing PVC's properties,promote PVC plasticization,obviously improve the thermal deformation temperature and surface smoothness of PVC products, and at the same time give PVC products higher surface hardness and rigidity.elevating their overall quality.

Lead Compound Stabilizer is comprises lead compounds, lubricants, antioxidants, and hydrotalcite as its primary constituents. serves a vital role in preventing PVC degradation, enhancing its heat and light stability.
