Plasticizers: Types, Uses, Classification, Selection & Regulation
Bio-based Plasticizers – They are based on epoxidized soybean oil (ESBO), epoxidized linseed oil (ELO), castor oil, palm oil, other vegetable oils, starches, sugars etc. Others – Includes Phosphates, Chlorinated Paraffins, Alkyl Sulfonic Acid Esters and more When added to polymer, these plasticizers provide several benefits as listed below.
Plasticizer Selection for Elastomers - Chemceed
A wide range of ester plasticizers are compatible with NBR, including adipates, phthalates, trimellitates, and epoxidized soybean oil (ESO). Chloroprene (neoprene) rubber (CR) Plasticizers are added to Polychloroprene Rubber to lower the glass transition temperature, reduce crystallization, and lower the cost.
- Are plasticizers compatible with BR?
- Plasticizers in Butadiene Rubber (BR) serve many functions. DOS, DBP, DOP, and some paraffinic, aromatic, or naphthenic mineral oils are compatible with BR. They can increase elasticity, lower processing temperature, improve blend dispersion, and enhance tackifying action.
- 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.
- What types of plasticizers can be used in Nr?
- In Natural Rubber (NR), Polyisobutylene, paraffin oil, DBP, DOP, and vulcanized vegetable oil can be used as plasticizers. These plasticizers are added to increase softness, improve filler dispersion, and aid in elastomer breakdown. NR is compatible with a variety of oil plasticizers including paraffinic, naphthenic, and aromatic oil plasticizers.
- How can plasticizers be used to make polymers soft and flexible?
- By adding plasticizers to compatible polymers, the materials can be modified in such a way that they become soft and flexible by decreasing their glass transition temperature. Plasticizers are classified according to their molecular structure into monomeric or polymeric types.
- Why are plasticizers added to elastomers?
- Plasticizers are used in elastomers for several reasons, including increasing softness or flexibility, lowering the glass transition temperature, reducing crystallization, increasing dispersion, or lowering the cost of the compound. Common plasticizers used in elastomer compounds are mineral oils and esters such as phthalates, sebacates, and adipates.
- 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).
