PP Honeycomb Core

Polypropylene honeycomb is also called pp honeycomb, plastic honeycomb, or thermoplastic honeycomb. This kind of honeycomb is made of non-toxic, tasteless and low density polypropylene which is good in strength, rigidity and heat resistance. (Traditionally, PP was used in electric products, such as clothes washing machine, microwave and so on.)


 
 

In order to allows better bonding of the polypropylene honeycomb to different panels , pp honeycomb can be pasted with non-woven fabrics on the both sides. To prevent the liquid glue from leaking into the honeycomb cell through non-woven fabrics, usually one layer of PP film can be put under the non-woven fabrics, acting as an barrier between the honeycomb cell and non-woven fabrics. Through this, the composite panel manufacturer can reduce glue consumption.
