WT class0 NBR Tube

Tubular structure, made of nitrile butadiene rubber as the main raw material by foaming, with completely closed foam flexible rubber plastic insulation material.

British Fire Rating Class 0 is a fire standard specified and specified in the documents approved by the Building Regulations of the United Kingdom. The Class0 rating must meet the following conditions:

Bs476-7 flame surface extension grade: the test must reach Class 1 (flame extension must not be greater than 165mm).

Plate structure, bS476-6 flame propagation index test again: the total flame propagation index is required, I≤12 and the single sub-index I1 ≤6.

Introduction

Mainly NBR/PVC as the main raw material, cooperate with flame retardant agent, foaming agent, curing agent, promoter and stabilizer, strengthening agent, such as additives, end spacing, mixing, extrusion, curing, foaming, cooling, cutting and become, has a small independent closed pore structure, heat preservation performance is good, good compression resilience, strong ability to resist water vapor permeability, good fireproof performance, low smoke non-toxic, Safe and reliable, long service life.

Application

It is widely used for thermal insulation and cold protection of various pipes and equipment in the high-end market of HVAC system to fully ensure the energy-saving effect of reducing cold and heat loss. It is widely used in various public places, industrial plants, clean rooms and medical and educational institutions.

Performance

: Better thermal insulation effect
initial thermal conductivity of 0.032W (M.K) 0℃ WINCELL rubber plastic adopts a special formula process, has a completely closed bubble internal structure, lower thermal conductivity is more stable, long-term operation energy saving effect is obvious.

: More security guarantee
WINCELL rubber and plastic obtained CQC certification. The combustion performance of its products reaches GB8624 standard B1 (additional grade: smoke S2, combustion droppings D0, smoke toxicity T1), is the customer's choice of win rubber and plastic confidence guarantee.

: Longer service life
wet resistance factor μ≥10000 WINCELL rubber and plastic completely closed foam structure can effectively prevent the infiltration of external water vapor, ensure the long-term stability of the physical properties of the material, prolong the service life of the product in various environments.

: More convenient installation
wide application, easy installation, short construction period, high efficiency, more economic!
