Shore is a measure of hardness. Din Shore A is 65-75 to 85 for rubber, ie rubber is much harder and can easily cause damage to the body. Today's cars have both plastic and thin metal in the body, which makes it difficult to lift without damaging the body. The pressure surface is softer and forms to the body rather than the other way around. Withstand all types of oils. The lifting blocks can withstand 3 -4 tons of pressure per cm².
Polyurethane lifting blocks but similar to rubber, approved for use by both professional workshops and private individuals. Fits all types of car lifts
Polyurethane lifting pads stronger than rubber. When you want even stronger lifting pads that can withstand a pressure of 3-4 tons (can become pressure marks if it is a sharp edge)
