Shanghai Pepsen manufactures standard and custom super abrasion resistant and heat resistant urethane
sheets and parts as per customer
requirements including drawings or samples. Hardness
is normally Shore 65A-60D. Urethane
Sheets made of Vulkollan equivalent material is about 6-8 times more abrasion-resistant than the normal urethane and it can work for
a long time under temperature up to 135 degree C (normal urethane withstands up to
80°C) and work in short period under temperature up to 165 degree C (normal urethane
withstands up to 120°C).
What is highly
abrasion resistant and heat resistant urethane Vulkollan equivalent sheet?
Vulkollan® is a trade mark of Covestro AG. It is known as “king of urethanes”. It is a super abrasion resistant urethane which is far superior to conventional urethanes in abrasion resistance and dynamic properties.
Vulkollan has
only one exclusive agent in China, and the cost is very high.
In 2004,
PEPSEN developed and researched replacement of Vulkollan successfully. (This cross-linked
elastomer comprises polyols (ester) with diisocyanates – naphthalene
diisocyanate (NDI).)
Over 60
customers from China and abroad use our NDI-Polyester sheet and parts and
replace Vulkollan successfully, while the cost is much lower. Some of them are
from World Fortune 500 and Volkswagen is one of them.
What are
advantages of Vulkollan equivalent urethane Sheet?
Why Vulkollan
equivalent urethane products always looks brown?
The natural color
of Vulkollan equivalent urethane is white, but it will change to yellow/brown
very quickly. Under ultra violet light, the color will change to dark/black.
Changes of colour, even unequal, will not affect the quality. Normally no
colorants will be added to Vulkollan equivalent urethane.
