BLACKROCK +

HIGH WEAR SHEETING ROUND GRAIN MATERIAL

Overview

Features

Natural rubber, black, 60 Shore A, with very good abrasion resistance.

Benefits

Performance Reliability Economy: reduce downtime and maintenance costs Long service life: lower hourly costs Safety

Applications

Hoppers, chutes, vibrating lines, truck boxes, etc., linings to protect equipment, especially at loading and unloading points, against very abrasive products, due to their very nature (very abrasive rocks, wood, chemical products, etc.), density and hardness (medium to high), shapes (salient, sharp-edged), large grain size, with dry or wet conditions and maximum temperature +70°C.

Areas of activity: sand and gravel quarries, glasssworks, construction and public works, civil engineering, building materials, mechanical engineering, transport, etc.

Advantages

Excellent shock impact, tear, and abrasion resistance
Good heat and ageing resistance
Noise and vibration propagation reduction
Protection against corrosion
Possibility to be produced with bonding layer for cold vulcanizing or with steel backing for mechanical fixing
Very high performance at low temperature
