Evaluating Plasticizers for Elastomers used in High
Low-temperature flexibility at low torsional twist force (T-2 and T-5) for plasticized compounds appears to favor the DB(3E)A plasticizer, but the others may be used without severe problems. All plasticizers tested provided better low-temperature flexibility than was obtained for the unplasticized control at all torsional twist forces.
Selecting Plasticizers for Adhesives and Sealants
A compatible plasticizer will give a greater viscosity response and will provide a clear dry film. 2. Viscosity Response The key evaluation parameters in choosing a plasticizer are: Viscosity and Viscosity Response Plasticizers will reduce the melt viscosity of hot-melt adhesives and 100% solids adhesives & sealants.
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.

Urethane/Rubber Plasticizers PB-3A, W-260, W-262, W-320
Features Effective in Plasticizing Polyurethane (TPU) Monocizer PB-3A and PB-10 are benzoate plasticizers with high polarity and that demonstration excellent compatibility with either type of TPU (polyether-based, polyester-based). PB-3A is effective in plasticizing polyurethane Improves elongation, tensile strength, hardness
- What is tp-90b plasticizer used for?
- Provides resistance to fungal growth in chloroprene rubber compounds. TP-90B plasticizer is used to develop optimum low-temperature flexibility characteristics in fuel hose, wire jacketing, cellular rubber goods, friction compounds, and a wide variety of molded and extruded products.
- 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.
- Does adding plasticizers reduce low temperature flexibility after aging?
- The addition of plasticizers did not cause loss of low-temperature flexibility after aging and may have aided in better numbers after water aging. Work with Tornac C indicates similar aging should be expected and shows that six additional plasticizers are compatible.
- What is the least permanent plasticizer order after heat aging?
- Coupling this with the unaged low-temperature flexibility and the knowledge of the Vamac B-124 MB shown earlier, the most to least permanent plasticizer order after heat aging is A1100, DADEG=DBEESS and DB(3E)A (Table V).
