MARL, Germany—Evonik Industries A.G. has launched a new plasticizer that it said includes "much sought-after properties," according to a Jan. 25 news release. To Continue Reading...
KURARAY LIQUID RUBBER - Elastomer Division | Specialty Chemicals
The high-viscosity synthetic rubbers are colorless, transparent, almost completely odorless and have low VOC values. The polymers of butadiene, isoprene and styrene have a low molecular weight, which is designed between solid rubber and plasticizer. KURARAY LIQUID RUBBER grades are co-vulcanizable with the base rubber to prevent migration.
Specialty Plasticizers for Rubber/Elastomers | Hallstar
Special application information to note on our plasticizer brands in nitrile rubber : Plasthall 226 (DEEBA) – HT, LT, hydrocarbon fluid and oil resistance, FDA Regulation 177.2600 Plasthall 7050 – Fuel B resistance, LT, HT, oil resistance, limited use with low ACN.
Markets > Rubber > Plasticizers and Processing Aids
Vanderbilt Chemicals, LLC has processing aids for rubber which reduce plasticity, improve mold flow and release, without adversely affecting physical properties. They also reduce compound plasticity, improves mold flow and release, has little effect on optimum physical properties.
Plasticizer Selection for Elastomers - Chemceed
Plasticizers are added to Polychloroprene Rubber to lower the glass transition temperature, reduce crystallization, and lower the cost. Mineral oils and organic esters are compatible with polychloroprene rubber. Aromatic mineral oils are used when reduction in crystallization rate is required, although their compatibility may be limited.
- Which plasticizer is best for nitrile rubber?
- Special application information to note on our plasticizer brands in nitrile rubber : Plasthall ® 7050 – Fuel B resistance, LT, HT, oil resistance, limited use with low ACN. Poor water resistance. Plasthall ® 83SS – Fuel C resistance, LT, HT. Plasthall ® 4141 – Good unaged and heat aged LT, #3 oil resistance, FDA Regulation 177.2600.
- Are polymeric plasticizers better than monomeric?
- Generally, polymeric plasticizers do not provide significant performance advantages over monomerics and are seldom used. Hydrogenated nitrile butadiene rubber (HNBR) is produced by hydrogenating the double bonds of the butadiene component of nitrile butadiene rubber (NBR).
- Which polymers need high polarity plasticizers?
- High ACN polymers require high polarity plasticizers, low ACN polymers require low polarity plasticizers. Polymerics used at greater than 15 PPHR are generally used in combinations with monomerics. Hallstar has a wide range of monomeric and polymeric plasticizers that can be used with NBR. APPLICATIONS
- Do polymeric plasticizers Rob curative effectiveness?
- Plasticizers containing double bonds (oleates and tallates) can rob curative effectiveness, as can naphthenic oils. Generally, polymeric plasticizers do not provide significant performance advantages over monomerics and are seldom used.
- What is natural rubber used for?
- The use of natural rubber in radial tires and other types of tires accounts for the largest share of natural rubber. Mechanical goods include hoses, conveyor belts, gaskets, seals, rubber and rubberized fabrics. The dynamic properties of natural rubber are used in springs, bushings and anti-vibration mountings.
- How is styrene-butadiene rubber polymerized?
- Styrene-butadiene rubber (SBR) is polymerized by two basic methods, emulsion and solution. SBR usually contains 29 percent styrene randomly dispersed with butadiene in the polymer chains. The emulsion and solution grades have basically the same ratios of styrene and butadiene.
