Plasticizer
A plasticizer ( UK: plasticiser) is a substance that is added to a material to make it softer and more flexible, to increase its plasticity, to decrease its viscosity, and/or to decrease friction during its handling in manufacture. Plasticizers are commonly added to polymers such as plastics and rubber, either to facilitate the handling of the
Synthesis and characterization of polymeric plasticizer
The prepared polymeric plasticizer was used in the preparation of nitrile rubber and nitrile–PVC rubber blend rubber sheets, where these sheets were tested for compatibility, tensile strength
Plasticizer - an overview | ScienceDirect Topics
Plasticizers are used to convert PVC, a rigid plastic, into a soft, flexible, and elastic material. A plasticizer that is compatible with PVC and exhibits low volatility, good permanence, and high efficiency is referred to as a primary plasticizer. A secondary plasticizer has the opposite characteristics of a primary plasticizer.
Uniplex | IMCD US
Used as a plasticizer for sealants, coatings, caulks, and adhesives. Uniplex 512: Low melting, waxy, solid plasticizer. The product is used as plasticizer for coatings application, as a thermoplastic processing aid and as a cleaner for adhesives. Utilized in thermoplastic polyesters (e.g. PBT, PCT, PET) to aid crystal growth during nucleation.
- What are the different types of softeners & plasticizers?
- Softeners or plasticizers are divided into non-solvent type and solvent type . The vulcanized rubber plasticized by the non-solvent softener is full of resilience, but will migrate to the surface of the product when the amount exceeds the appropriate amount.
- What is the viscosity of a plasticizer?
- The viscosity is 80CP (20°C). FDA qualified products (rubber products, adhesives, etc.). (2 ) It is used to plasticize synthetic rubber, vinyl resin and cellulose resin. It is one of the most used plasticizers.
- Can vulcanized rubber be used as a plasticizer?
- But the solubility of vulcanized rubber is low, and sometimes it shows signs of bleeding. Generally not used, but can be used as cold-resistant plasticizer. 10.2.2 cotton seedoil (Cotton Ceed Oil ) (1 ) Properties: light yellow to dark red oily liquid. The specific gravity is0.915～0.932. Freezing point -6～-1℃ . The iodine value is88～128.
- What is a rubber softener?
- 1. Rubber softener It acts as a lubricant in rubber molecules and can promote the relaxation of polymers, so that the chemical substances used in rubber processing are called softeners. Softeners are also called plasticizers, process oils, and compatibilizing oils.
- Is vulcanized rubber a solvent based softener?
- The vulcanized rubber plasticized by the non-solvent softener is full of resilience, but will migrate to the surface of the product when the amount exceeds the appropriate amount. In addition, when the solvent-based softener exceeds the appropriate amount, it acts as a solvent and cannot maintain the specific state of the product.
- 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.
