Products

Antitack NP-97 is a Pure zinc stearate dispersion of small particles, developed especially for dip tank equipment. The stearate particles are only partially hydrophobic due to the special production process. Therefore the antitack agent within the dilution shows the tendency to rise to the upper third of the dip tank. While the compound leaves the dip tank, it passes through the region of highest concentration and gets the optimum coverage of an-titack agent.

Mediaplast PM is a synthetic aromatic plasticizer based on polyalkylbenzene (bi- and trialkylated aro-matics), which is mainly recommended for the use in elastomers with low to medium polarity, i. e. NR, IIR, BR, SBR, EP(D)M for example, but also CR, CM/CSM, EVA and PNR. Especially in polychloro-prene the often used, expensive ester plasticizers can be replaced completely.

Silanogran Silanogran SI-69/GR 70 offers improvement of mixing properties e. g. reduction in Mooney viscosity, better processability when mixing, calendering and extruding and influences the physical-mechanical data of the vulcanizates favorably.

Silanogran PV is the 50 % granular form of a trimethoxy-silyl-group containing low molecular poly-butadiene (formerly Polyvest 25) on a mineral carrier. The pure liquid polymer is sticky and highly viscous. Our granular form provides easier handling, avoids inaccuracy and insecurity while dosing and incorporating the material into the rubber compound.

Kezadol GR is a soft 81.5 % calcium oxide granule coated with special dispersing agents, for use as a desiccant in rubber compounds which are cured on micro-wave systems, LCM or hot air. Moisture which is present in all rubber chemicals, especially fillers, will be absorbed and the calcium oxide will change to calcium hydroxide after reaction with the moisture. This reaction will happen while storing the uncured rubber compounds.

Kezadol PCI is a surface treated calcium oxide powder for use as an effective desiccant. The calcium ox-ide is coated by a chemically indifferent hydrocarbon. Due to this preparation Kezadol PCI has a reduced air pollution. Additionally there will not be any unintended reaction with humidity.

Mediaplast 60 is a highly effective chemical peptizer for natural and Isoprene rubber, based on the well-known dibenzamidodiphenyldisulfide (DBD). However, it does contain an activator/catalyst system which enables the product to show superior efficiency in comparison to the products you find on the market today.

Antitack BTO-7 is a pigment-free antitack agent for the treatment of unvulcanized rubber compounds based on different biodegradable detergents in combination with anti-foam and anti-corrosive additives. The product was developed especially for the treatment in batch-off equipment working in dipping or spraying system. The use of Antitack BTO-7 results in an extremely proper production site and in a very low wear and tear of the machinery.

Mediaplast NB-4 is a special adipine acid plasticizer at an exceptionally reasonable price for the use in polar polymers like NBR, H- and XNBR, CM / CSM, CR, ECO, etc. Mediaplast NB-4 is, due to its relatively low volatility and also because of its extremely low setting point, suitable for heat-resistant as well as cold flexible rubber articles (see technical data).

Kettlitz-Dispergator DS is a dispersing agent improving flow and extrusion properties of rubber compounds. The material, based on a water-in-oil emulsion of higher alcohols, esters and aliphatic fatty acids, is recommended to be used in EPDM and EPM, in NBR and butyl rubber compounds.

Actigran 50 and 70 are 50 % resp. 70 % preparations of trimethylolpropantrimethacrylate (TRIM) bound to inert carries in granular form. The use of Actigran 50 or 70 normally increases the cross-linking density of cured rubber compounds

Mediaplast AT is a very effective process aid to improve flow properties and to reduce the tackiness of rubber compounds regardless of the polymer used. Processing of CR and ACM compounds in par-ticular is significantly improved by adding a small amount of Mediaplast AT. It improves the demolding properties of technical rubber parts. The sticking of uncured compounds to internal mixers, open mills and conveyor belts will be visibly diminished by the use of Mediaplast AT.
