EPS is a foamed plastic and is generally used for plastic products such as packaging and toys. Due to its large size, it is difficult to recycle. However, the value of its reuse is high. In general, we recycle it into pellets, reuse it into plastic products, and change its physical shape.
Its processing technology and uses are as follows:
1, production of flame retardants. 2. Prepare impact plastic. 3, production of lightweight building insulation materials.
4, can use non-solvent heat medium defoaming recycling process, the process is to put the waste polystyrene foam into the defoaming tank, add heat to a certain temperature of the heat medium, make contact with the foam and with defoaming shrinkage The materials fall together into a heated sump and the defoamed material is then separated from the media used to obtain a defoamed regrind. Mainly to reduce the size and facilitate transportation.
5. High recovery pyrolysis process.
6, solvent regeneration.
7, waterproof membrane.
8, fiber reinforced sound insulation board.
9, concrete foam insulation board.
10, metal, wooden doors and windows and glass sealant.
11, asphalt enhancer.
12, plant fiber reinforced insulation material.
13, impermeable leak trapping agent.
14, multi-functional resin glue.
15, with rust antirust paint
16. Regeneration by physical methods. Waste polystyrene foams can be made into heat-insulating materials and building materials by this process. This method is widely used.

The film has excellent heat sealing performance and excellent transparency, is one of the main packaging composite base materials, used in the production of high-temperature boiling film, vacuum aluminum coating film, the market is very optimistic.Moreover, with the development of domestic production equipment, some of the technical indicators have reached the international advanced level.As a result, the threshold to enter the film production is lower and lower.Because of this, some enterprises rush to import the flow of film production line in order to reach the designated position, the higher the level, the better, while leaving the market demand and the return on investment aside, which will cause huge waste of resources.
