During the investigations, the adhesion of PPS fiber elastomer composites under quasi-static (T-Test) and static/dynamic loading (Eplexor) was determined in tensile mode at different temperatures. Therefore, PPS fibers with different sizings and various 2-step wet-chemical coatings were used.Weiterlesen...

Lignin (and/or lignosulphonate) is the second most abundant renewable organic material on earth, immediately after cellulose, in wood, straw and other plant tissues, represent the main component of cell wall, represents a vastly underutilized natural polymer, it is produced as a by-product in pulp mills in large quantities and poses huge disposal problem.Weiterlesen...

Part III. Effects of Oil Types and Contents on the Properties of Carbon Black Filled Compounds The influences of DAE-, TDAE- and MES-oils on the properties of carbon black filled NR and NR/SBR blend compounds are discussed. The properties are strongly affected by oil contents, but less by the oil types. Compounds with DAE have the lowest Mooney viscosity but highest complex viscosity and Payne effect. SEM micrographs show that carbon black is finely dispersed in the compounds, except for MES which shows slightly poorer filler dispersion than TDAE and DAE. The use of TDAE and MES in NR clearly influences the properties related to changes in Tg and viscoelastic behavior. Use of MES gives the best elastic response in NR, while TDAE gives the best response for NR/SBR blend vulcanizates.Weiterlesen...

Lanxess officially inaugurated its new neodymium butadiene rubber (Nd-BR) plant in Singapore on August 27. Located next to the company’s existing butyl rubber plant on Jurong Island, the world-scale facility represents an investment of approximately Euro 200 million.Weiterlesen...

For the manufacturing of fibre-reinforced, elastomeric media hoses the projectile injection technique, a special injection moulding process, is examined as an alternative to established extrusion process. Our investigations show that in an one-step injection moulding process complex, fibre-reinforced media hoses can be made of liquid silicone rubber. Process parameters can be used to adjust specifically the part quality such as the residual wall thickness.Weiterlesen...

The blow molding process offers the possibility of reproducible, fully automatic and therefore cost-efficient mass production of complex hollow bodies.Weiterlesen...

Diene-based rubbers, such as natural rubber (NR) and styrene-butadiene rubber (SBR), have been widely used in diverse industries. For diene rubbers, sulfur and the peroxides are most commonly used vulcanizing agents.Weiterlesen...

The advent of the European tyre labelling regulation EC/1222/2009 and tightening of the US Corporate Average Fuel Economy (CAFE) regulations have seen major improvements in the fuel efficiency offered by tyres[1]. Similar labelling systems have also been implemented in Brazil, South Korea and Japan, with China set to follow suit in the near future [2,3]. These drivers have seen increased utilisation of silica filler in place of carbon black. Recycling might be an alternative source to supply the need.Weiterlesen...

The flow behavior of rubber compounds is often influenced by the occurrence of flow anomalies like wall slip or the slip-stick effect.Weiterlesen...

Belgian chemicals producer Solvay, Brussels, has begun production at its new fluoroelastomers (FKM) plant in Changshu, China, as part of its ongoing strategic site expansion. The company wants to meet booming demand for its specialty polymers from Asia‘s fast-growing automotive industry and multiple other high-end markets.Weiterlesen...
