We produce rubber-plastic foamed heat preservation products

We produce rubber-plastic foamed heat preservation products (PVC/NBR) by introducing newest technology and craft and automatic processing line. The major materials we use are NBR/PVC,which are undergone ban bury,vulcanization and foam,Therefore,the main characteristics are:Low density,close bubble structure,low thermal conductivity, Water vapor transmissibility extremely low,low water -absorptive ability,Fire-proof performance well,superior anti-agde performance,good flexibility,easy to install. This product is suitable for a wide temperature range,from -50℃ is to 110℃ ,also has good anti-adge performance and durability.Its fire +proof capacity achieves the standard of BS476 CLASS1 CLASS0.

Normal wall thicknesses of 1/4”, 3/8″, 1/2″, 3/4″,1″, 1-1/4”, 1-1/2″ and 2” (6, 9, 13, 19, 25 , 32, 40 and 50mm).

Standard Length with 6ft (1.83m) or 6.2ft(2m).

Advantages of product

1. Air conditioner rubber insulation tube
2. Low conductivity&heat conductivity
3. Closed cell pipe insulation
4. Good fireproof
5.The rubber foam tube has very good stability and can play a good role in preventing fire.
6.The rubber foam tube is flexible, so it is easy to install when it needs to be bent.
The insulation tube is made of NBR and PVC. It doesn't contain fibrous dust, benzaldehyde and
Chlorofluorocarbons. Moreover, it has low conductivity &heat conductivity, good moisture resistence and Fireproof.
