Plasticizers: Types, Uses, Classification, Selection & Regulation
Most commonly used phthalate plasticizers include: DEHP: Low molecular weight ortho-phthalate. Still the world’s most widely used PVC plasticizer DINP, DIDP: High molecular weight ortho-phthalates Aliphatic dibasic acid Esters – These include chemicals such as glutarates, adipates, azelates and sebacates.
Eastman Plasticizer A to Z List - Eastman Chemical Company
Eastman 168 Renew 20 non-phthalate plasticizer performs as good as or better than most ortho-phthalate plasticizers. In general-purpose plasticizer applications, it offers good performance properties, excellent low-temperature flexibility, resistance to extraction by soapy water, and excellent nonmigration properties.
Plasticizers in Paint & Coatings: Uses, Types and Selection
Good stability to heat and ultraviolet light Broad range of compatibility, and Excellent resistance to hydrolysis Di-iso-octyl phthalate (DIOP) DIOP is like DOP, an all-purpose plasticizer for polyvinyl chloride, polyvinyl acetate, rubbers, cellulose plastics, and polyurethane. Di-iso-nonyl phthalate (DINP) & Di-iso-decyl phthalate (DIDP)
SELECTION OF A PLASTICIZER FOR PRODUCING MATERIALS BASED ON
powders are almost completely devoid of plasticity and, as a consequence, there is an extremely weak adhesion interaction between powder particles in the compact. Therefore, in practice, when molding the powder, Si 3 N 4 is mixed with a plasticizer. The most common method for molding Si 3 N 4 powder is pressing in closed molds.
Dry powder coating of pharmaceuticals: A review - ScienceDirect
The physical stability of the theophylline pellets powder coated with HPMCAS was evaluated in a range of conditions. The powder coated pellets were stored at either 25 °C/10% RH or 25 °C/60% RH. Formulations containing only TEC as the plasticizer were characterized with the highest agglomeration tendency at 60% RH which was reflected in the
- How to choose a plasticizer?
- The choice of the plasticizer is dependent on the requirements that have to be met for the final product and the conditions around that product’s use. This may include low volatility, high permanence, low temperature flexibility, flame retardancy, high thermal stability and saponification resistance.

WOTAIchem provides reliable polycarboxylate superplasticizer powder for you. All PCE powder have stable quality. We provide team service for your OEM solution.
- Why is plasticization important?
- Plasticization is the process of making the final plastic product more flexible. By incorporating the right type and amount of plasticizer you can tweak your formulation. Hence, selecting the right plasticizer for a specific application is very critical to make the product softer. Plasticization can occur both internally and externally.
- What are the benefits of polymeric plasticizers?
- Check out the table below for the benefits of polymeric plasticizers. As we shift to sustainable ingredients, bio-based plasticizers continue to gain further importance. They can be used as a phthalate alternative. They also lower our dependence on fossil fuel-based feedstock. The common feedstock for this class of plasticizers is mentioned below.
- How to choose a general-purpose plasticizer for PVC?
- While selecting a general-purpose plasticizer for PVC, the main attributes to be checked are: Among them, regulation is an important decision factor while selecting plasticizers. In recent years, there has been a lot of discussion on phthalate plasticizers. But in fact, not all phthalates are prohibited.
- 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.
