Entwicklung von Thermoplastischen Vulkanisaten (TPV
The suitable conditions to prepare TPV with fine properties were found to use EV as a cure system, DCBS as an accelerator and a rotor speed of 100 rpm at ~190 °C for 6 min. TPV developed from ENR
While melamine is widely used in flexible foams as a fire retardant, trichlorophenyl phosphate has been the preferred agent for use in many rigid foams. However, the introduction of specifications stipulating halogen-free additives has led to the increased use of phosphorus esters, red phosphorus (which can quickly acidify a polyol blend and

Rubber has certain unique properties which makes it suitable to produce rubber products which are widely used in various industrial applications. Rubber is water repellent. It is resistant to alkalies and weak acids. Rubber has elasticity, toughness, impermeability, adhesiveness, and electrical resistance.
US Patent for Composite part Patent (Patent # 10,239,293
Elemental sulphur and sulphur donors that are optionally to be used additionally in preferred embodiments are used in the rubber mixture for use for the elastomer part in the inventive composite preferably in a total amount in the range from 0.1 to 15 parts by weight, more preferably 0.1 to 10 parts by weight, based on 100 parts by weight of
decisive adhesion-promoting effect where bonding of rubber to steel cord is concerned. The adhesion therefore improves as the proportion of sulfur is increased (4 7 phr). Sulfenamides should be used as accelerators, Vulkacit® DZ (DCBS) giving the highest bond strength values. High zinc oxide levels promote the adhesion. Direct bonding
Konson TBSI Rubber Accelerator
Its physical properties and dynamic properties of cured rubber are similar with NOBS and DCBS cured rubber. It can also replace the blend of primary amine accelerator TBBS or CBS and scorch retarder CTP and be used alone, which makes it ideal for thick articles requiring a balanced cure and provides improved reversion resistance both during
WESTCO™ ZBPD is a non-staining, non-blooming liquid, fast curing secondary accelerator for rubber compounds, especially EPDM and NR. It may be used with standard rubber accelerators but is most commonly used along with other non-nitrosamine generating accelerators. When used with sulfonamides in NR, it improves reversion resistance.
Vulcanization & Accelerators Nocil
widely used accelerators in the rubber industry for the production of wide variety of goods such as cycle tyres and tubes, footwear, beltings, hoses and other moulded and extruded goods. Thiazoles are activated by Zinc oxide / Stearic acid combination and produce flat cure with vulcanizates having
Out of these, melt mixing is the most widely used due to its simplicity and industrial acceptability. The main objective of the present work is to study the effect of OMMT on the DCBS accelerator 1.00 1.00 1.00 1.00 TMQ 2.00 2.00 2.00 2.00 UK). The vulcanized samples were kept in an air-circulating oven at 100°C for 48 h
