Polyurethane & Rubber | Minepetrax Nusa Persada

Polyurethane Product

Our Polyurethane features the following qualities:

The main advantage of castable polyurethanes over rubber is their abrasion resistance. High wear-resisting -Anti-resistant performance is from 0.01-0.10 （cm3）/1.61km, Duration will be longer 3-5 times than rubber.
Low friction coefficient, when compared to Rubber; extremely slick when wet
High load resistance, far superior to Rubber, metals and other plastics in its ability to absorb energy, sounds and vibrations
Chemical resistance, excellent with oils, acids, bases, hydrocarbons
Hydrolytic stability is formulated to resist water absorption without losing its performance
High acid and alkali resistance
Good Vibration absorption
Can be machined to the required surface finish and profiles.
High strength -Break strength and bearing capacity are higher than rubber.
Noise abatement, excellent to suppress sound
The combination of high tear resistance and a high modulus is what gives polyurethanes this advantage.
Wider durometer range option to choose. With the high hardness, the Polyurethane parts still have good elongation and elasticity. The hardness of Polyurethane parts is at Shore A60-D80
Lining sectors for screw classifiers
Significantly lower moulding costs
Ozone resistance
Poly can be offered in various colours which allows colour coding of parts or possibly matching the company’s logo.
Oil resistance: As a kind of high molecular compound.
Polyurethane parts have high radiation resistance.

Rubber Sheeting

Premium Grade (40±5 Shore A, 27 MPa, 3–25mm Thick, 1500mm Width, 10000mm Length)
Eco Grade (40±5 Shore A, 18 MPa, 3–20mm Thick, 1500mm Width, 10000mm Length)
Orange Rubber sheeting is designed for harsh conditions and has therefore a very high NR- Polymer content. It also comes with a Bonding Layer for easy and fast application.
Black60 is an excellent rubber lining product well suited for dry wear and impact areas because of its abrasion properties. NMC Black60 is a Premium lining with CN Bonding, compound widely used in machineries and equipment. Typical applications of Black 60 can be seen in vibratory feeders, chute lining, etc.
BROMO BUTYL RUBBER - BIIR is a black rubber with 50 +/-5 Shore A hardness and with an excellent bonding layer furnished rubber, based on a Butyl (Bromine Isoprene Isobutyl Rubber) compound with outstanding chemical resistance features.
UVR45 is a UV Resistant Rubber (45±5 Shore A, 22 MPa, 3–20mm Thick, 1500mm Width, 10000mm Length)
UVR65 is a UV Resistant Rubber (65±5 Shore A, 22 MPa, 3–20mm Thick, 1500mm Width, 10000mm Length)
