Plasticizer - an overview | ScienceDirect Topics
Plasticizer efficiency is used to describe the ability of a plasticizer to make the product softer and is reported as a ratio of the slope of the hardness versus plasticized concentration to the slope of that found for DOP. The relationship of hardness and plasticizer concentration expressed in phr (parts per hundred resin) is shown in Figure 3.

Compared to the traditional Ni catalysts, the Pd composite catalysts used in this technique lead to significant advantages including higher catalytic efficiency, shorter reaction time, lower temperature, an HHPA selectivity of 100%, and constant product quality.
Effects of molecular design parameters on plasticizer
Performance metrics including each plasticizer’s thermodynamic compatibility with PVC (measured by the heat of mixing Δ H), plasticization efficiency (measured by the reduction in the Young’s modulus Δ Y compared with pure PVC), and migration tendency (measured by the MSD curves of the plasticizer in the PVC matrix) are reported and
Selecting Plasticizers for Adhesives and Sealants
Plasticizers are one of the commonly used additives in adhesives and sealants formulations. They improve the performance of adhesives by creating much-needed flexibility, optimizing viscosity, toughness, set time functionality, impact resistance, and even adhesion.
Phthalate-Free High Efficiency Plasticizer Improved
Title: Phthalate-Free High Efficiency Plasticizer: DOWANOL LoV 485 Glycol Ether Author: The Dow Chemical Company Subject: Provides information on the key features, benefits, applications typical product properties, results of ASTM C920 testing and performance data such as glass transition temperature depression testing.
- Which plasticizer has the best plasticizing efficiency?
- It's worth noting that PSCH has the best plasticizing efficiency attributed to the C–Cl bond on the side. According to the similar compatibility principle, except for hydrogen bonding, the existence of C–Cl bond in PSCH increases the compatibility of plasticizer and PVC.
- How to choose a high-performance ester plasticizer?
- The rubber compounder must evaluate ester plasticizers for compatibility, processability, permanence and performance properties. The study of these properties by the rubber compounder will contribute to the selection of a high-performance ester plasticizer. 1.
- What are high performance plastics?
- The aim is to have applications that run smoothly, with minimum maintenance, at the best cost to performance ratio. Within our material portfolio, you will certainly find the high performance plastics you need for your applications. High performance plastics typically have a permanent operating temperature of more than 302°F.
- What is a general performance ester plasticizer?
- Some general performance ester plasticizers used in the marketplace today are DOA, DIDA, DIDP, DOP, DINP and other phthalates and adipates made from straight-chain alcohols of 7–11 carbons in length. Ester plasticizers are commonly used only for their as-molded, low-temperature contribution.
- Which plasticizers are used in stretch PVC films?
- Considering the tensile properties, all samples will probably show adequate performance when used as stretch PVC films with slight differences between them as follows: The plasticizers ATBC, DEHT and polyadipate showed lower plasticization efficiency than the others since samples 2, 4 and 6 showed the highest tensile strength values.
- Can plasticizer improve the plasticity of polyvinyl chloride (PVC)?
- Plasticizer is an important assistant in the production process of polyvinyl chloride (PVC), which can effectively improve the plasticity of PVC. However, the durability and plasticizing effect of traditional phthalate plasticizers need to be further improved.
