Recycled PS

XPS polystyrene recycle material is used to produce board foam. It goes through processes of pre-expansion, curing, molding, drying, and cutting. It can be made into foam products of different densities and shapes, as well as foam board materials of various thicknesses. They are widely used in construction, insulation, packaging, refrigeration, daily household items, and industrial casting industries. They can also be used for manufacturing exhibition venues, product displays, advertising signs, and toys. Currently, to meet building energy-saving requirements, they are mainly applied in external wall insulation, internal wall insulation, and floor heating. XPS recycled plastic pellets belong to the category of plastic pellets. Recycled plastic is made by recycling used new materials or discarded plastics through a screw machine, then cut into pellet-shaped plastic pellets by a pelletizing machine. They can be classified into grades 1, 2, and 3.

Grade 1 refers to the use of raw materials without floor trimmings, or known as trimmings, some are nozzle materials, gel head materials, etc., with relatively good quality, not used. During the process of processing new materials, small trimmings are left, or the raw material quality is not good. Particles processed from these have better transparency, their quality can match that of new materials, thus it is a material or special grade material.

KRJ-RS01:

XPS(Big White)  MI，meltindex：7-15

Grade 2 refers to raw materials that have been used once, but most of them are processed using imported high-pressure granulation. The imported large IF film is for industrial use and has not weathered, so its quality is also good, with good transparency. At this time, the quality of the processed pellets should be judged based on the brightness of the pellets and the surface roughness.

KRJ-RS02:

XPS(Sino-Belarusian)  MI，meltindex：15-25

Grade 3 refers to raw materials that have already been used more than twice. The particles processed from these materials are not very good in terms of elasticity, toughness, and other aspects.

KRJ-RS05:

XPS(Tea ingredients)  MI，meltindex：20-30

It is suitable for  board foam such as insulation boards and extruded plastic boards.
In order to improve production efficiency, it is necessary to use a certain ratio of the new GPPS.
