What is Extruded Polystyrene – XPS?

Image
  Extruded Polystyrene – XPS Generally, polystyrene is a synthetic aromatic polymer made from the monomer styrene, which is derived from benzene and ethylene, both petroleum products. Polystyrene can be solid or foamed. Polystyrene is a colorless, transparent thermoplastic, which is commonly used to make foam board or beadboard insulation and a type of loose-fill insulation consisting of small beads of polystyrene. Polystyrene foams are 95-98% air. Polystyrene foams are good thermal insulators and are therefore often used as building insulation materials, such as in insulating concrete forms and structural insulated panel building systems. Expanded polystyrene and extruded polystyrene are both made from polystyrene, but EPS is composed of small plastic beads that are fused together and XPS begins as a molten material that is pressed out of a form into sheets. XPS is most commonly used as foam board insulation. Extruded polystyrene (XPS)  is also a thermoplastic polymer. Extruded polyst

Why recycled polystyrene foam and EPS are your best choices

Image
  We found two important facts about expanded polystyrene (also known as   EPS or polystyrene foam ). The first thing they point out is that EPS packaging is recyclable. The second thing is that it is a small part of our landfill and solid waste stream. EPS also makes up less than 1% of total municipal solid waste (by weight and volume). This is very encouraging considering that EPS is considered by many to be the unfit child of the recycling world.      Where did all this EPS and polystyrene foam come from?  Polystyrene was discovered by German pharmacist Eduard Simon in 1839. When he separated it from the natural resin, he didn't actually realize what he had discovered. Eighty years later, organic chemist Hermann Staudinger discovered that Simon had actually discovered a plastic polymer. Staudinger was eventually awarded the Nobel Prize in Chemistry for all his polystyrene-related research, and in the 1930s, BASF scientists discovered a way to produce polystyrene commercially. At

6 Steps To Make a EPS Mould

Image
  6 Steps To Make a EPS Mould     1. First according to the customer supply of samples or drawings, planning the product three-dimensional drawings. Make  EPS mould  planning according to customer requirement.Through the process requirements and manufacturing process method to determine the mould processing plan and processing materials. 2. Plan to make 2D drawings of EPS muold after making sure, then make foam models by model masters. 3. The model is delivered to the caster to cast the mold and parts. 4. After the die is cast, the program is made by the programming engineer and processed by the CNC machining center. 5. After finishing, each core, cavity and spare parts are further processed, and the accuracy and scale are checked for consistency with the data. 6. After each part is finished, the installer will assemble the scattered parts together, thus a complete set of  EPS moulds   is made.Check whether the test products are qualified,The products can only be delivered to the custo

Features and operation methods of EPS foam molding machine

Image
  The EPS foam molding machine has the characteristics of complete functions and convenient parameter adjustment. Closed mold, feeding, foaming, mold, gas and automatic control, but also allows computer control to produce foam products with multiple heating methods Old machine molds that can be used in complete soil environments, in the case of no changes in plants, the The machine can be in good condition, so that the products meet the requirements of automatic vacuum forming machine. The foaming machine has compact structure, space saving, reliable performance, convenient maintenance, labor saving, steam quality saving, and raw material saving. EPS foam molding machine   is semi-automatic learning, a little bit, no training, every 2-4 operating machines. The foam molding machine adopts imported hydraulic system at the same time, and increases the clamping force to improve the speed of the mold, the molding cycle is short, the molding machine is automatic molding machine More energy-s
