添加剂是添加到 聚合物 在加工过程中增强或改变其特性。例子包括稳定剂、增塑剂、阻燃剂和紫外线吸收剂。添加剂可以提高性能、加工性能和耐久性。
碳酸钙是由钙、碳和氧（ CaCO3 ）组成的化合物。它在塑料工业中常用作填充材料，以增强塑料制品的各种性能，如降低成本、提高刚度、增加体积等。
Fiber glass compound refers to a composite material consisting of plastic (polymer) and glass fibers. This combination results in a reinforced material with increased strength, stiffness, and dimensional stability.
Plasticizers are additives incorporated into polymers or plastics to improve flexibility, durability, and processability. They work by increasing the mobility of polymer chains, reducing intermolecular forces, and enhancing the material’s ability to bend and stretch. Commonly used in PVC (polyvinyl chloride) formulations, plasticizers make the plastic more pliable and suitable for various applications such as films, cables, and coatings. Popular examples of plasticizers include phthalates, adipates, and citrates.
A plastic matrix refers to the polymer component or matrix material in a composite, where reinforcement materials like fibers or fillers are embedded. The plastic matrix holds these materials together, providing structure and determining the overall properties of the composite material.
A polymer carrier resin is the base polymer that acts as a carrier for additives, fillers, or pigments in a masterbatch or compound. It provides a matrix for incorporating other materials, contributing to the overall performance and characteristics of the final plastic product.
Polymer compounding involves the process of combining polymer resins with various additives, fillers, or reinforcements to create a compound with specific properties. Compounding aims to tailor the polymer to meet desired performance criteria.
聚丙烯 (PP) 是一种热塑性聚合物，广泛用于各种应用，包括包装、纺织品、汽车零部件等。它以其耐用性、耐化学性和多功能性而闻名。
Titanium dioxide is a white pigment widely used in the plastics industry to provide opacity and brightness to plastic products. It is commonly employed as a white pigment in masterbatches and compounds.
