Engineered Polypropylene Core PP Honeycomb

Light, Strong, Tough, Cost-Effective Plascore PP Honeycomb is a tough, lightweight and ductile polypropylene material that provides efficient and optimum mechanical performance in composite sandwich structures. PP Honeycomb is an excellent alternative to traditional core materials such as plywood, balsa and foam used in the manufacturing of consumer and industrial products. Available in a wide range of sheet sizes and facings, PP Honeycomb is engineered for ease of use in many mainstream manufacturing processes, is readily available and can be modified to meet specific requirements for...
