Polymethacrylimide foam refers to a foam with a C-C chain as the main molecular chain and an imide structure in the molecular side chain, which can be manufactured by a variety of methods. PMI foam is currently the heat-resistant foam with the highest strength and rigidity (180~240℃), which can meet the requirements of medium and high temperature, high pressure curing and prepreg process.

 

It has good compatibility with various types of resins and is suitable for use as a core material in a high-performance sandwich structure. It can replace the honeycomb structure and is isotropic. It is easy to be machined into various complex cross-sectional shapes. It does not contain any Freon, it is an environmentally friendly material, and its fire resistance meets FAR 25.853 and AITM and other relevant standards. It represents the latest development field of high-performance polymer structural foam.

PMI foam is mainly used in aerospace, radar antenna covers, CT medical bed boards, wind power helicopter blades, high-speed trains and building materials. It is currently the hardest structural core material under the same density and is a new type of very promising development. Composite materials. Like traditional materials, when PMI foam is used, it must first be cut to be better processed into various required shapes to meet the needs of different places of use.

 

Therefore, the cutting machine of PMI foam material is the first step in the application of PMI foam material to actual production, so the cutting machine is a very critical equipment for the application of PMI foam material.
