LIPREN X 1112 is an aqueous, colloidal dispersion of polymerised of 2-chlorobutadiene (1,3). Vulcanised LIPREN X 1112 has a very little tendency to crystallize. Lipren X 1112 is mainly used in the production of dipped goods, but also for the production of flame retardant foams. It is either foamed or used to impregnated PU foams.

Application Advice/Typical Applications

Goods processed with LIPREN X 1112 show a better flame-retardant behaviour than similar goods made with natural rubber or other synthetic rubbers. Their flame-retardant behaviour can be further improved by adding suitable inorganic flame-retardants, e.g. zinc borate or aluminium hydroxide. Products made with LIPREN X 1112 are characterized by a high resistance to ageing, weathering, ozone and heat. They show a good resistance to a number of organic chemicals, including various acids. LIPREN X 1112 requires zinc oxide not only as a crosslinking agent but also to improve the resistance of the products to weathering, ageing and heat. ZnO also acts as an acceptor of hydrogen chloride, which is slowly released in the course of time, depending on the temperature. In some applications it is necessary to add an extra portion of antioxidant to ensure sufficient ageing protection (e.g. a non-staining antioxidant agent). Consequently users should examine from case to case, whether it is needed to add even more antioxidant or not.

The dispersion can be destabilised if the pH is too low. This can occur as a result of the slow, but permanent, release of hydrochloric acid. If the pH falls below the specification limit, it should be re-adjusted to its initial value before processing the dispersion by adding aqueous KOH of 5 % concentration. Avoid any contact of the product with metals which are not corrosion-resistant.

Shipping and Storage

Store at an even temperature of between +5°C and +35°C avoiding frost and direct sunlight. Stir product before use. If stored according to these conditions and in the original unopened containers, the dispersion will be stable for 6 months following delivery. Product should be used as soon as possible after opening. During processing, storage and transport of the product, contact with metals unprotected against corrosion (likewise non-ferrous metals) has to be avoided.
