Plasticizers - ASTM International
Plasticizers are liquids of molecular weight greater than that of solvents—to limit volatility—but are not solids, such as alloying polymers, etc. It should be noted that cross-linked resinous coatings significantly reduce plasticizer loss due to diffusibility and volatility.
ASTM International - ASTM D2383-19 - Standard Test Method for Testing
ASTM D2383-14 March 1, 2014 Standard Practice for Testing Plasticizer Compatibility in Poly (Vinyl Chloride) (PVC) Compounds Under Humid Conditions 1.1 This practice defines the conditions for the exposure and qualitative evaluation of poly (vinyl chloride) (PVC) compounds for plasticizer compatibility under humid conditions.
Plastics Standards - Standards Products - Standards & Publications
Plastics Standards. ASTM's plastics standards are instrumental in specifying, testing, and assessing the physical, mechanical, and chemical properties of a wide variety of materials and products that are made of plastic and its polymeric derivatives. During processing, these synthetic or semisynthetic organic solids have a very malleable
ASTM International - ASTM D3465-21 - Standard Guide for Purity
1.1 This gas chromatographic guide covers a procedure for extending the range of purity determination of monomeric plasticizers beyond that now determined by other methods. Due to the need to volatilize the plasticizer, only monomeric plasticizers having definitive boiling points and a molecular weight less than 1000 Daltons, such as dioctyl phthalate, are applicable to this guide.
Dibenzoate Plasticizer Technology for Sealants - ASTM International
Dibenzoate Plasticizer Technology for Sealants Source Dibenzoate plasticizers are widely utilized in latex caulks because they are compatible with the polymers used in that application. Dibenzoates are also known to be used in the polymer side of two-part insulating glass polysulfide sealants.
- What are ASTM plastics standards?
- ASTM's plastics standards are instrumental in specifying, testing, and assessing the physical, mechanical, and chemical properties of a wide variety of materials and products that are made of plastic and its polymeric derivatives.
- Which plasticizer has the best mechanical properties?
- Of the plasticizers we synthesized, the best film mechanical properties were provided by OC plasticizer, containing primarily propylene glycol monoacetate, but also propylene glycol diacetate, acetic acid and propylene glycol in its mixture.
- Are bio-based plasticizers sustainable?
- 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. As the name says, biobased plasticizers are majorly based on:
- What is a plasticizer chemistry?
- Plasticizers are the most used additives in the plastics industry. They are generally available as non-volatile, colorless liquids. They improve the properties of the polymer. With several plasticizer chemistries available in the market choosing the right one can be daunting. In this guide, you will read more about:
- Are alternative plasticizers effective?
- The research confirmed that the alternative plasticizers introduced by us are more effective than commercially available ones, exhibiting lower hydrophilicity and superior mechanical properties compared to samples plasticized with traditional plasticizers. Moreover, these properties were found to be even better after ageing for 10 months. 1.
- What is a polymeric plasticizer?
- Polymeric plasticizers are typically made from aliphatic dibasic acids such as adipic acid and diols. They are primarily valued for their permanence. These plasticizers are generally classified as polyesters, not adipates. Many have low solvency for PVC and high viscosity. Both these factors can make processing f-PVC compounds difficult.
