Plasticizer Selection for Elastomers - Chemceed
TBEP is one such plasticizer that is compatible with FKM. Polyacrylate rubber (ACM) Plasticizer use with ACM is limited dues to the high operating temperatures used. Polymeric plasticizers, TOTM and TBEP can be used in some cases. Ethylene acrylic (AEM) Both monomeric and polymeric ester plasticizers are compatible with AEM.
Proviron Inc. - Proviplast, specialized plasticizing solutions
Plasticizers from Proviron are commonly used in polar rubber products such as nitrile rubber, acrylate elastomers and chlorinated polymers. Our Proviplast rubber plasticizers improve overall flexibility, with low temperature properties and high temperature aging stability. In rubber products they are suitable for applications such as seals
Plasticizers: Types, Uses, Classification, Selection & Regulation
A primary plasticizer enhances elongation, softness and flexibility of polymer. They are highly compatible with polymers and can be added in large quantities. For example: up to 50% of vinyl gloves are made up of plasticizers, which make the PVC flexible and soft enough to wear.
Plasticizer
Sebacate - based plasticizers provide excellent compatibility with a range of plastic materials and synthetic rubbers (specifically nitrile rubber and neoprene), superior properties at low temperatures, and good oil resistivity. Some examples are: Dibutyl sebacate (DBS) Di- (2-ethylhexyl)sebacate, Di-octyl Sebacate [15] (or DOS plasticizer)

These high performing silicone products offer: Outstanding mechanical and electrical insulating properties. Shortened development time.
- 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.
- 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.
- 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.
