“CLD” LONG-LIFE RUBBER COMPOUNDS
General characteristics
This is a POLYETHER POLYURETHANE ELASTOMER (EU) which, similarly to polyester-based products, offers excellent mechanical characteristics, wear and abrasion resistance, elasticity and low gas permeability. Resistance to mineral oils and fuels is lower than the POLYESTER type, especially at high temperatures (around 100°C). On the contrary, it offers EXCELLENT RESISTANCE TO HYDROLISIS. The hardness range can vary from 55 to 90 Shore A. Excellent bonding to metal.
This rubber is also used to produce technical items subjected to mechanical stress, and vulcanisation can be performed both by compression and by injection, as well as in autoclave for roller production.
Compound storage conditions
This rubber compounds can be stored at room temperature avoiding direct sources of light or heat and keeping in its original PE packaging. Under these conditions, integrity can be guaranteed for up to 3 months which can be further improved, if necessary, storing it at temperatures below 0°C to preserve its excellent properties for longer period of time.
Molding indications
This rubber is moulded at temperatures ranging from 135°C to 145°C.
