The peeling strength of PVC knife coated tarpaulin and coated tarpaulin
The peeling strength of PVC knife-coated tarpaulin and coated tarpaulin refers to the force required to separate the coating from the base fabric. This is a critical measure of the bond between the coating and the fabric, which ensures the durability and performance of the tarpaulin.
1. PVC Knife-Coated Tarpaulin
Peeling Strength:
Typically ranges from 8 to 15 N/cm (Newtons per centimeter).
Factors Affecting Peeling Strength:
The adhesion quality of the PVC coating to the base fabric.
The thickness and uniformity of the coating.
The type of base fabric (e.g., polyester or nylon) and its surface treatment.
2. Coated Tarpaulin (General)
Peeling Strength:
Typically ranges from 5 to 12 N/cm.
Factors Affecting Peeling Strength:
The type of coating material (e.g., PVC, polyethylene, or acrylic).
The coating application method (e.g., knife coating, calendering, or lamination).
The quality of the base fabric and its preparation (e.g., scouring, heat setting).
Key Differences:
PVC Knife-Coated Tarpaulin: Generally has higher peeling strength due to the thicker and more uniform application of the PVC coating, which adheres strongly to the base fabric.
Standard Coated Tarpaulin: May have lower peeling strength depending on the coating material and application method.
Applications:
PVC Knife-Coated Tarpaulin: Used in applications requiring high durability and resistance to peeling, such as heavy-duty truck covers, industrial curtains, and outdoor shelters.
Coated Tarpaulin: Suitable for lighter applications where peeling strength is less critical, such as temporary covers, tents, and groundsheets.
For specific peeling strength values, it is essential to refer to the manufacturer's specifications, as they can vary based on the product's intended use and quality.
