Silicon Carbide (SiC) is one of the most popular high performance tribo-materials, which has been commercially available for more than twenty-five years. Its features include:
· Excellent abrasion and wear resistance
· Excellent corrosion resistance
· Low coefficient of friction
· Low coefficient of thermal expansion
· High thermal conductivity
· Hardness greater than Tungsten Carbide
Different grades of Silicon Carbide are available as following:
· Reaction Bonded Silicon Carbide (RB SiC) - a very economical material which gives excellent wear characteristics, as well as good chemical resistance.
· Sintered Silicon Carbide (SSiC) - the absence of free silicon makes it most resistant to chemically-aggressive fluids, and ideal for high temperature applications.
· Graphite-Loaded Silicon Carbide - this is a composite of silicon carbide and free graphite. Graphite is added to RB SiC (RB SiC + C) or SSiC (SSiC + C), to improve tribological behavior by enhanced lubricity.

PE Shrink Tunnel adopts double motors to blow the hot air reach every corner inside the tunnel to make sure the perfect performance of shrinking. Meanwhile, the Shrink Tunnel has adjustable heavy cool air, so it can ensure the shape of the shrinking perfectly.
Stailess steel heating tubes and strong blowing motor ensure high heating efficiency, large air volume and uniform air circulation.
Soild Metal rods wrapped by heat-resistance silicone tubes make the conveyor rollers strong and resilient
The PE Shrink Tunnel and POF Shrink Tunnel always use to packing beverage, beer and mineral water, cans, glass bottles with tray or carton
At the Same Time, PE Shrink Tunnel adopt double fan motors make the heat air inside the tunnel evenly. Meanwhile, different products combination can be sealed perfectly and automatically. And closed packing for Shrink Tunnel to realize water proof and light proof. On the other way, Shrink Packing Machine adopts PE film to meet long distance transport and won't broken after frequent handling.
Remove the shrinking tunnel. Products could be packed by no poison PE shrinking film.
Suitable for floor boards, ceramics, furniture, electric appliances or other shapes of products closed shrinking packing
