The light guide plate is an optical material. The main material used is PMMA (acrylic or Plexiglas). Design principles is from the laptop LCD screen, which is a high-tech products transforming the line light source into the surface light source. Optical-grade acrylic as base material using the backlight technology of the LCD display screen, through the light with high light transmission rate, calculated by the computer-guided light, make the light guide plate molding through refraction the surface light uniform.

ABS/HIPS refrigerator board co-extrusion extrusion line adopts high tech co-extrusion technology, three-roller calendars calibrating, world famous brand components, which is used to produce multilayer ABS/HIPS boards, widely used in family appliance field, such as inner case of refrigerator, washing machine, out shell of air conditioner, etc. Sanitary board: use PMMA-ABS co-extruded compound, and retains the characteristics of acrylic surface rigidity and gloss, but also take into account the advantages of ABS plate impact resistance. Forming well, high temperature, low temperature resistance, wear resistance, corrosion resistance and good mechanical properties are all good for sanitary products such as bath, shower room, sauna room, wash tank.

The new environmental protection EVA automotive interior plate production line developed by our company successfully put into production in large quantities, the equipment in the technical field of all reached the world advanced level, and changed the history of such equipment are imported, truly achieve the environmental protection requirements can be recycled after use, by a number of experts affirmation and praise. The company focuses on performance improvement and formulation. The sheet can be used as car roof insulation, decoration materials, packaging materials, waterproofing and insulation and construction materials.

PE waterproofing geocell is of using a kind of high-grade polyethylene resin as the main raw material, adding a certain amount of filler and stabilizer, plasticizer, UV absorbers and other auxiliary materials, waterproof material after mixing, extrusion, cooling process, volume, meter, packaging etc. PE waterproofing geocell making machinery has the advantages of compact structure, convenient operation. The extrusion machinery can Configure different components according to customer requirements, used for the production of single-layer and multi-layer composite products. It can increase the winding devices, used in the production of enhanced product or surface-composite non-woven fabrics and PE decorative film products etc.

PVC crust foamed plate has such characteristics as sound separation, sound absorption, heat separation, temperature-keeping, etc. The material is incombustible, it is safe for use. All series of products have property of moisture proof, mildew proof, water resistance, its vibration resistant effect is good. All series of products have property of weathering proof, its luster may remain forever, it is not easy to be ageing. This product is light, storage & transport, construction are rather convenient. This product can be worked with normal tools for wooden material. Drilling, sawing, nail, planing, bonding can be conducted like wooden material. It is suitable for thermal shaping, thermal bending and fold processing. It can be welded, it can also be bonded with other PVC material. The surface of this product is smooth, it can be printed. ( Clean the surface before printing.).

This line specially used for producing PP/PE/PS/ABS single layer or multi-layer sheet or plate, suitable in the fields of packing, stationery, chemicals, construction, household appliances and so on. Sheet specifications: Usual sheet width: 700,900,1020,1200,1300,1400,1500,1700,1800,2100,2200mm, Usual sheet thickness: 0.5-2mm, 1.5-10mm, 6-20mm,3-30mm.

Diffusion sheet is applicable to LED lighting lamps. such as down lights, grille, high-grade aluminum lamps. Diffusion plate suitable for side light LED lighting, like flat panel lights, advertising light boxes, professional film viewer, usually used with light guide panel. Diffusion plate is light diffusion layer of the substrate such as PC/PMMA/PS, met with the refractive index difference of medium (proliferation of particles), multi-angle, multi-directional refraction, reflection and scattering phenomena in order to light diffusion effect, provides a uniform surface light source to display lighting components. PS light diffusion sheet is of gravity of 1.05, much lighter than PC, PMMA and so on, greatly reducing the transportation costs. Transmittance is above 75%, and to be large-scale used for its cheaper but relative in performance with the PC, PMMA and so on.
