Overview of Common Thermoplastic Polymers Used in Nonwoven Extrusion

In the nonwoven plastic mesh and sheet extrusion industry, selecting the right thermoplastic material is key to product performance and efficiency. Below is an overview of some of the most widely used petroleum-based polymers in this field:

Polyethylene (PE)

Polyethylene is the most widely used thermoplastic polymer, available in various grades such as LDPE, LLDPE, and HDPE. It offers excellent flexibility, moisture resistance, and processability. PE is commonly used in agricultural mesh, packaging nets, and protective plastic covers.

Polypropylene (PP)

Polypropylene is a lightweight polymer with high mechanical strength and thermal resistance. Its chemical resistance and cost-effectiveness make it a top choice for producing industrial meshes, flexible packaging, and lightweight plastic products.

Polyvinyl Chloride (PVC)

PVC is a tougher material compared to PE and PP, offering strong resistance to chemicals and physical stress. With the addition of plasticizers, flexible PVC can also be used in specific mesh and coating applications that require more softness.
