T-PHC series polypropylene honeycomb core is a lightweight core that delivers excellent flex properties, including longitudinal stiffness and compression strength. The PP honeycomb core can be widely used in industrial lightweight constructions, especially for vehicles and automobiles.

Advantages and Application

Significant weight saving

Lightweight PP honeycomb means lightweight transporting facilities. Therefore the transportation speed goes up and the cost goes down.

Excellent compression and impact resistance

The honeycomb structure is good at abstracting the external force and reduce the effect of collision. It is utilized in car bumpers, sporting protective armors and other fields.

Effective resistance to sound transmission

Qualified for soundproofing equipment for mobile vehicles and other transporting facilities.

Waterproofing and corrosion resistance

The PP honeycomb products are strong enough to be applied into high moisture conditions and strong corrosive environment, such as harbor construction and floating raft at sea.

Production

As a core material of sandwich panels, the T-PHC series PP honeycomb core is made with a packaging film of polypropylene as standard. This prevents the ingress of resin into the cells during processing, and therefore safeguards uniformity of mechanical characteristics, which also reduces the quantity of adhesives.
