The material difference between PP and PA Corrugated tubing

Polypropylene Corrugated


Polypropylene(as known as PP)

is a semi-crystalline thermoplastic. It has high impact resistance, strong and tough mechanical properties, the melting point of PP is about 167 ° C, heat resistance and resistance to various organic solvents and acid and alkali corrosion. It is widely used in various applications in the industry.

Polyamide Corrugated Tubing


Polyamide (as known as PA)

is a polymer formed by the polymerization of monomers containing carboxyl and amino groups through amide bonds. There are many types of synthetic polyamides according to the composition of their main chains. The PA corrugated tubing made by Good Gi Co., Ltd is made of PA6, with a melting point of about 220°C, which has better impact resistance and corrosion resistance, and is superior to PP in terms of high-temperature resistance, mechanical properties or chemical properties, and has a better appearance with glossy. But its cost is higher than PP material.

The Difference Between The Application Of PP And PA Corrugated Tubing:

Because of its small molecular mass, Polypropylene Corrugated tubing is often used on vehicles, and the Corrugated tubing used on electric vehicles is mostly identified by orange color. If the protection is not required so much on mechanical strength, choosing PP corrugated tubing will be more cost-effective.

Because of its high toughness and hardness, PA Corrugated tubing is widely used in environments where automation equipment is bent, or in external environments that need to withstand stress.

For example: Outdoor cables. Because of high heat resistance makes PA Corrugated tubing used in high-temperature environments

Specification Difference Between PP And PA Corrugated Tubing:

The outer diameter of the Corrugated tubing is controlled by the mold, and the inner diameter is controlled by the wind pressure, so the Corrugated tubing of Good Gi can be produced with the same size as PP and PA, and there is no difference.
