Eastman 168 SG (Sensitive Grade) Non-Phthalate Plasticizer
Product description Eastman 168 SG non-phthalate plasticizer is an enhanced grade of the industry-leading Eastman 168 non-phthalate plasticizer, specifically targeted at more demanding applications such as medical devices, toys, childcare articles, and food contact applications.
Plasticizers: Types, Uses, Classification, Selection & Regulation
It is almost colorless and odorless oily liquid. It is very slightly soluble in water but soluble in alcohols, hexane etc. while miscible and compatible with all the monomeric plasticizers used in PVC compounding. Melting point: 43°C (45°F; 230 K) Boiling point: 244-252°C at 0.7 kPa.
Eastman Product List for General Purpose Plasticizers
Eastman 425 is a non-phthalate plasticizer for vinyl compounds and plastisols. It is compatible with PVC as well as PVC /VA copolymers. The performance of Eastman 425 plasticizer is equal or better than other higher-solvating plasticizers. Eastman TEG-EH (Triethylene Glycol Bis (2-Ethylhexanoate)) plasticizer is usually blended with
What is the best alternative to DEHP for medical-grade PVC
Purity. If processed in truly dedicated equipment, DOTP can be produced nearly free of DEHP contamination. DOTP plasticizer producers specify a DEHP content of less than 50 parts per million, but almost all shipments contain significantly less than that. By contrast, TOTM can contain as much as 2,000 ppm of DEHP and is never free of it.
PHTHALATE PLASTICIZERS - University at Buffalo
Plasticizers are usually inert organic materials with high boiling points and low vapor pressures. Esters are commonly used due to their favorable physical interactions with high-molecular-weight polymers. This physical interaction causes the polymer and plasticizer to form a “homogenous physical unit.”
- How are plasticizers classified?
- Plasticizers are classified based on their chemical composition. It is important to understand the influence of structural elements on the properties of plasticizers and their effect on base polymers. For example, the presence of elements like alcohols in a homologous series of phthalates, and adipates.
- What are natural product type plasticizers?
- Vegetable oil derivatives are the most widely used natural product type plasticizers. Products consisting of triglyceride esters of unsaturated fatty acids (e.g., soybean oil, linseed oil) in which the double bonds in the fatty acid residues have typically been epoxidized have been commercial products for decades.
- What is a primary plasticizer?
- 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.
- 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.
- 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:
- 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.
