Polymer stabilizers
Phenolic benzotriazoles (e.g. UV-360, UV-328) and hydroxyphenyl-triazines (e.g. Bemotrizinol) are used to stabilise polycarbonates and acrylics, [25] oxanilides are used for polyamides and polyurethanes, while benzophenones are used for PVC . Strongly light-absorbing PPS is difficult to stabilize.
Plasticizers: Types, Uses, Classification, Selection & Regulation
DIDP plasticizer increases the flexibility of the plastic/ plastic coating. They are more permanent (less volatile, less water extractable) than DINP. Its good heat stability and electric insulation makes it a preferred choice for heat-resistant electrical cords, car interiors and PVC flooring.
Plasticizer - an overview | ScienceDirect Topics
Plasticizers such as DIDP or DPHP are used for products needing greater permanence; automotive interior trim applications will focus on DIDP, DPHP, L9P, L911P, L11P, and trimellitates to meet fogging requirements.
Plasticizers & Processing Aids - HM Royal
See all Products. Processing aids and plasticizers are chemical additives used in compounds to increase the plasticity, fluidity or lubrication of a material. These processing aids are suitable for use in plastics and rubber compounds. Plasticizers soften polymer compounds in order to improve processing, lower compound viscosity and increase
- Are biopolymers a good substitute for conventional plasticizers?
- The use of natural and/or biodegradable plasticizers, with low toxicity and good compatibility with several plastics, resins, rubber and elastomers in substitution of conventional plasticizers, such as phthalates and other synthetic conventional plasticizers attracted the market along with the increasing worldwide trend towards use of biopolymers.
- Can bioplasticizers improve the processing properties of rubber compounds?
- Addition of the bioplasticizer strongly improve the processing properties of the rubber compounds. Desirable mechanical properties and thermal stability can be achieved by adding the bioplasticizers in rubber compounds. Rubber-filler interaction, plasticizing efficiency, and cross-linking density decide the tensile strength of the polymer matrix.
- Do plasticizers reduce the kinetics of rubber compounds?
- The results revealed that the application of plasticizers resulted in the deceleration of the curing kinetics and reduction in torque increments, pointing to the decrease in the rubber compounds’ viscosity. This was subsequently confirmed by the rheological measurements. The plasticizers softened the rubber matrix as well as the biopolymer filler.
- Which Plasticizers improve tensile strength?
- In general, it can be concluded that the best performing were plasticizers based on polyethylene glycol, improving both the elongation at break in more than 50% and tensile strength in more than 40 MPa. Materials with applied glycerol demonstrated poor tensile strength but the highest elongation at break (over 100%).
- Do plasticizers soften rubber compounds?
- This pointed to the softening effect of plasticizers on rubber compounds and a reduction in the compounds’ viscosity, which was clearly confirmed from the rheological measurements. The higher the amount of plasticizers, the lower the viscosity.
- 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.
