Plastics & Rubber - Evonik Industries
Plasticizers are commonly added to polymers, such as plastics and rubbers, to facilitate handling during production or meet the end product's application demands. They make the raw material softer and more flexible, increase its plasticity and decrease viscosity or friction.
Plasticiser loss from plastic or rubber products through
Other polymer systems that use plasticisers include acrylic polymers, polyamides, polyolefins, polyurethanes, certain fluoroplastics, and elastomers. 7 Particularly, plasticisers are commonly used...
Specialty Plasticizers for Rubber/Elastomers | Hallstar
Most of the acrylics require a plasticizer to achieve low temperature performance. Many monomerics are too volatile to be of value because of the post cure requirement. Low temperature performance can be best achieved with polymerics as well as TP-759 and TegMeR 812.
Plasticizers: Types, Uses, Classification, Selection & Regulation
Most common plasticiser chemistries include citrates, benzoates, ortho-phthalates, terephthalates, adipates, azelates, sebacates, and trimellitates. Plasticizers are the most common additives used in the plastics industry. But, selecting the right plasticizer for an application has always been a daunting task.
Selecting Plasticizers for Adhesives and Sealants
Plasticizers are one of the commonly used additives in adhesives and sealants formulations. They improve the performance of adhesives by creating much-needed flexibility, optimizing viscosity, toughness, set time functionality, impact resistance, and even adhesion.
- 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
- 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.
- 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.
- Why do we use plasticizers for elastomers?
- Plasticizers are commonly used only for their as molded low-temperature contribution. Effective plasticizers for the above-named elastomers should have resistance to volatility and extraction at elevated temperatures. Weight changes and low-temperature flexibility after laboratory aging are indicators of plasticizer permanence.
- Which monomeric plasticizer is most effective?
- Of the monomeric plasticizers tested, DB(3E)A and DADEG appear most effective. It should be noted these are the highest molecular weight of the monomeric esters tested. The low viscosity (and molecular weight) of polymeric A1100 appears to offer low-temperature flexibility and permanence suitable to acrylic elastomers.
- How do plasticizers affect polymers?
- Plasticizers are substances which, by virtue of their polar or polarizable structure, weaken the secondary valence forces of polymers. 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.
