Hunan Rifeng Composite Co.,Ltd （ Rifeng? ）’s parent company has long been engaged in R&D of special high molecular polymer materials an d has an experienced team for polymer product R&D, application research, test, an d analysis. The company s technical team has won more than 100 national an d provincial scientific research awards. They have rich experience in the research of specialty foam materials.
All these years, the high-performance PMI foam cores used in China was imported from Germany. The ROHACELL PMI structural foam has long been a monopoly in China s PMI foam market. A few years ago, we developed the PMI foam cores an d realized the domestic quantity production. Now we put our main product Rifeng? PMI foam which with excellent performance an d cost-effective on the international market to serve more industrial fields.
Rifeng? specializes in R&D, production, an d marketing special high-performance structural foam core materials. The main product is polymethylacrylimide （PMI） foam which have obtained national invention patents. Our product performance has reached the international advanced level （same as Ｏr above than ROHACELL）. We have an advanced PMI foam production line with an annual output of 8000m3, an d the second production line under construction. It is the first domestic manufacturer that can produce large-thickness PMI foams. Now, we have more than 10 specifications of Rifeng? PMI foam products. PMI foam has high specific strength, high specific modulus, high thermostable, an d closed-cell property. Under the same density conditions, the strength, modulus, an d tensile strength of PMI foam are much higher than other foams. So the PMI foams are the first choice for composite sandwich core materials.
Rifeng? PMI structural foam core material have been applied in Aerospace, Aircraft/Helicopter, UAV（unmanned aerial vehicle）, Radome, Antenna, Rail Vehicles, High-Speed Ships, Wind Power Blades, Medical Equipment, Sports Equipment, Audio Equipment, Fishing Floats an d other fields.
We also provide PMI structural foams （radio absorption, wave absorption, fire retardant）. Deep sea buoyancy material, phenolic foams, cross-linked polystyrene, carbon foams an d other special composite materials an d its products.
Moreover, we provide complete post-processing services. Including CNC machined, thermoformed, In-mold foaming an d so on.
Our goal is to be a domestic first-class PMI foams development an d production base, to provide customers with first-class quality PMI foam products, to be a world-class PMI foams expert.
