what is recycled ABS sheet
Recycled ABS sheet is a common type of plastic sheet. For the recycled ABS sheet required by customers, we provide two solutions:
1. 100% Recycled ABS sheet
The ABS sheet produced in this way will have pores and pits on the surface, and the tensile strength and impact strength of ABS will decrease, but the cost advantage is that it is 35-45% lower than that of pure new materials. It is recommended to be used in non-load-bearing structural parts or Class B appearance parts. If you just want to reduce costs, you can choose some cheaper materials such as PET, PE, etc.
2. New-recycled-new ABS sheet
Provide customers with plastic sheets with new materials on the surface and recycled ABS in the middle. The surface layer uses 20-30% new materials (thickness is about 0.8mm), the core layer is 70-80% recycled materials, and gradient fusion is achieved through five-layer co-extrusion technology. This can maintain the surface, performance, and price of ABS sheets in a balance. The overall mechanical strength is maintained at more than 85% of the new material, and it can also ensure that we have a certain profit margin.
The influence of recycled ABS sheets on vacuum forming
Recycling ABS sheets will affect material performance changes, processing technology adjustments and product quality.
Decreased mechanical properties
The tensile strength and impact toughness of recycled ABS sheets may be reduced, and the products are prone to brittleness or breakage.
Mold design adjustment
Complex structure molds may be insufficiently filled due to poor fluidity of recycled materials, and the mold structure needs to be simplified or vents need to be added.
Appearance defects
Recycled ABS sheets will be made into dark colors to improve the defects of uneven color. You can choose to use new material to match the color of the surface ABS sheet to improve the appearance color.
Decreased fluidity
Recycled ABS sheets are prone to uneven stretching, local thinning or cracking during vacuum forming. The heating temperature can be appropriately increased or the heating time can be extended to improve the fluidity of the material.
Impurities and contamination
The recycled material may be mixed with dust, impurities or other plastics (such as PVC), resulting in obstruction of melt flow and bubbles, dents or stratification on the surface of the product.
Optimization of molding parameters
Appropriately increase the suction force to ensure that the material fits the mold tightly, select products with the smallest stretching degree, extend the cooling time, and prevent product deformation.
