PP Foam Tape Procurement Guide

(Disclaimer: Some of the information in this article is sourced from the internet. Please carefully identify and use it.)

Product Overview: PP foam tape is made through physical foaming technology, with low density (0.3-0.5g/cm³), and combines lightweight, high elasticity, and shock absorption performance. It is an ideal material for Cable Filling and buffering layers.

Key performance indicators (for reference only, not used as procurement standards)

• Foaming rate: ≥ 70%, closed cell rate>90% (ASTM D3575 standard).
• Compression rebound: The recovery rate after 50% compression is ≥ 85%.
• Environmental friendliness: Free from toxic substances and compliant with EU REACH standards.

Application scenarios

Suitable for buffer layers in new energy cables (such as charging station cables), mining cables (MCP), and precision instrument cables.

Procurement precautions

• Foam uniformity: Require suppliers to provide testing reports to ensure even distribution of pores.
• Customization requirements: Support customization of width (10-50mm) and thickness (3-10mm) according to cable cross-section.
• Transportation and storage: Avoid heavy pressure or exposure to sunlight to prevent the collapse of bubbles.

Frequently asked questions

Q: How can foam tape avoid moisture absorption?

A: Choosing a model with surface coating (such as PE film) can reduce the water absorption rate to less than 0.5%.
