Classification of plasticizers - Oxoplast
Plasticizers (softeners) are softening substances which reduce the intensity of intermolecular interaction and increase the mobility of polymer chains. As a result lower glass transition temperature, hardness, strength and increased flexibility of polymer is achieved . Plasticizers also act as an internal lubricant.
Plasticizers – Benefits, Trends, Health, and Environmental Issues
Plasticizers soften the PVC to make it flexible and bendable. This opens up a huge range of possibilities for new applications. One of the main benefits of plasticizers is the durability they confer onto PVC applications, which can ensure high performances for up to 50 years.
Selecting Plasticizers for Adhesives and Sealants
Another method of classifying plasticizers is based on their performance such as: General-purpose plasticizers; High-performance plasticizers ; Specialty plasticizers; Today, phthalates remain the most popular choice because they usually provide the best all-round performance and they are low in cost. However, phthalates are suspected carcinogens.
Current Status of Plasticizer Research | SpringerLink
Benzoate-based plasticizers made from C 8 –C 12 alcohols have the following exceptional properties: (1) comprehensive plasticization performance with small side effects; (2) good compatibility with most synthetic resins and rubbers; (3) low release leading to high stability; (4) high resistance to heat and weather, low volatility, good low-temperature flexibility, low extraction, no tendency
A Strategy for Nonmigrating Highly Plasticized PVC
Phthalate esters are still the most powerful plasticizers and dominate the plasticizer market due to their great plasticizing effect and low-cost, although phthalate plasticizers can migrate to
- Are plasticizers considered softeners?
- Plasticizers are often referred to as softeners. In the 1920’s, researchers discovered that many esters of the polycarboxylic acid group, such as phthalic acid and phosphoric acid, were able to react with high polymers to form a homogeneous physical compound.
- 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.
- How do plasticizers affect polymers?
- Plasticizers are substances which, by virtue of their polar or polarizable structure, weaken the secondary valence forces of polymers. 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.
- 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.
- Which Plasticizer makes PVC soft?
- To make PVC soft, the Plasticizer must have the following essential performance properties. Polynt can provide the most suitable Plasticizer for any application to achieve this.
- 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.
