PEF (Polyethylene Foam) Insulative Materials

Introduction to the features of PEF material
Polyethylene high-rate foaming material is a kind of sealed foaming plastic.
polyvinyl chloride with flame-resistant material etc. be chemically reacted in high pressure for second times. PEF be usually applied in keeping the bottom pipe of the air-conditioner warm.
Advantages:
1.small Heat-conduct coefficient ,prevent the heat escaping
2.better steam-resistant ,anti-aging, lower cost
keep the refrigerator warm and keep it away from the steam and moisture ,no necessary to add another layer to prevent the steam and moisture
water permeation
Still keep warm even be soaked in the water ,not like the material absorb the water and lose to keep warm.
