UV-cured protective case

I. Product Overview

Photochromic glass fiber prepreg tape is developed after summarizing the advantages and disadvantages of similar products. The product's development direction is to be used as a protective material for directional crossing of pipelines.

The product is mainly used for the sealing of new pipeline sections, the sealing of horizontal crossing sections in new pipelines, and the overall wrapping of horizontal crossing sections in new pipelines.

II. Product Features

High strength, high rigidity, and excellent resistance to deformation. As a pipeline crossing protective material, the essential requirements are high strength and excellent resistance to deformation to prevent tearing by gravel within the borehole.

High tensile strength, excellent crack resistance.

High adhesion for 3-layer PE and fused epoxy powder coating. All photo-sensitive fiberglass jacket products are non-adhesive by themselves and must be bonded to the substrate through an intermediate low-coating material.

High surface hardness. Just like steel materials, to achieve high scratch, wear, and piercing resistance, surface hardening treatment is necessary while enhancing the overall strength of the material. This is why gears, cutting tools, shafts, and shaft sleeves we commonly use are all surface hardened.

No hollow joint overall wrapping technology. Hollowing, especially continuous hollowing, is one of the main reasons for the damage to the pipeline when it passes through the outer protective coating.

High shrinkage rate. The pre-impregnated film for photo-sensitive glass fiber reinforced plastic cases has a high shrinkage rate of 1.5-3%.
