PVC board and EVA board What is the difference, which is good flexibility
PVC is a hard foam board similar to a foam board. Buy the PVC board when the attention to thickness and density, the thicker the greater the density the more expensive.
There is also a material called EVA COS props used in more soft and easy to plastic but not convenient color and carved pattern. EVA has good flexibility
PVC is a polymer that uses a chlorine atom to replace one of the hydrogen atoms in polyethylene.
PVC is the most important feature of flame retardant, it is widely used in fire protection applications. But PVC in the combustion process will release hydrochloric acid and other toxic gases.
? EVA: ethylene-vinyl acetate copolymer is low foaming polyethylene foam plastic. Is a new type of environmentally friendly plastic packaging materials, with good cushioning, seismic, heat insulation, moisture, chemical corrosion, etc., with non-toxic, non-absorbent. Has a good anti-vibration: resilience and high tension, high toughness, With good shock / cushioning performance
