1. Over Three times of Polyurethane rubber in Strength and Abrasion resistance True value of " Horest " is demonstrated to rubber rollers and rubber parts tend to wear and abrade intensively under the use condition that high speed revolution is linked at a high temperature and be fatigued intensively.
-
2. Over level with EPT rubber in heat resistance (150°C)and weatherproof Since there is few oil resistance and lacks of rubber elasticity in the high hardness,EPT rubber cannot be used in some machine. That became possible at the advent of " Horest"
-
3. Over level with NBR rubber in oil resistance and printability "Horest " enable you to use the roller under high temperature and required high unti-fatigue and weatherproof that NBR rubber cannot put up with.
-
4. Low heat building up in high speed load and high speed revolving Heat build-up of " Horest " rubber under high speed load and high speed revolving is half compare with usual rubber material used for high speed revolving. So it enable you to reduce frequency of your maintenance subustantially.
-
5. High rubber resilience even high hardness (over 80 Shore-A of rubber hardness) Polyurethane rubber has excellent performance in the rubber elasticity in high hardness. But it is weak in heat, therefore it has a big imperfection of melting under intense abrasion and heat building up. " Horest " enable you to prevent this melting. It is a mysterious rubber that has specific performances that no other rubber material has wide area performance as this.
Horest
RUBBER ROLLER WITH ULTRA DURABILITY THAT CHANGED THE APPRECIATION OF RUBBER
