EPS (Expanded Polystyrene) is the name of the expanded Polystyrene, produced in the form of granules containing flammable Bentan (C5H12) gas. EPS particles have a composition of 90 – 95% Polystyrene and 5 – 10% of gas generators such as pentane or carbon dioxide. Through the process, EPS enlargement granules increase the size of the adhesive, and when put into production, they will be formed into products depending on the purpose of use.
Production process:
Primary EPS seeds are expanded through the temperature of 90°C to expand 20 to 50 times. Next, put in the mould (block) heated (100°C) with the appropriate time to produce EPS foam – EPS plastic also known as EPS foam.
Product Foam – EPS plastic shaped from the size of the blooming so in the volume M3 contains from 3,000,000 to 6,000,000 small sticky honeycomb-like particles, in each small particle cell after hatching contains 98% of the Air, which has the advantages of thermal insulation, thermal insulation and sound insulation.
Characteristics of EPS:
- Absorb impulse and withstand good compressive force: very effective when used as packaging to protect goods, electronics, fragile materials, scratches
- High strength, not affected by mould, temperature and dust: protect products very well during storage and transportation.
- Insulation, soundproofing: EPS plastic helps keep food fresh, avoiding condensation. Ensure foods such as seafood, vegetables are distributed and transported safely while still ensuring freshness and inherent shape.
