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.

Dispergator FL is a very effective and multi-purpose processing aid for the use in natural and synthetic rubber. Dispergator FL is generally used to improve rubber compound flow and extrudability for the production of profiles, hoses and technical rubber parts. By using Dispergator FL an economical production of high quality products is possible.

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.

Antitack NP-97/TY-40 is a highly concentrated dispersion of zinc stearates. By means of new tech-nologies and high quality raw materials the zinc stearate content could be increased to more than 40 %.

Mercapto silane for sulfur cured rubber compounds which are containing silica, clays or metal hydroxides as filler. It is suitable for all elastomers and recommended to use if an improvement of technical results, such as tear strength, modulus, compression set or abrasion is required.

Mediaplast WH is a Processing aid and homogenizing agent with non-staining properties in order to improve the stickiness of synthetic rubber compounds. Especially in NBR, EPDM, SBR and EVA the application of Mediaplast WH results in shorter mixing times and better homogeneity.

Kettlitz-Silanogran VES is a 50 % dry liquid in granular form of a triethoxyvinylsilane containing oli-gomeric alkyl groups. It is used in peroxide cured rubber compounds which are filled by silica, silica earth (Sillitin), clay, other fillers containing SiO2-groups or aluminum hydroxide.

TAC/GR 50 is a 50 % and TAC/GR 70 a 70 % triallylcyanurate (TAC) in granular form. TAC/GR gran-ules are more stable and better applicable in automatic weighing machines than TAC/GR 70, whereas the latter contains a higher amount of active substance.
