PVC Plasticizers and Stabilizers Following Safer Sustainable
Evonik’s Plasticizer Products for Improved Gelation for Soft PVC Formulations Starting, Evonik offers three plasticizer products of note, namely: VESTINOL 9 DINP is a very cost-effective, general-purpose plasticizer very useful in soft PVC formulations with a broad processing temperature window.
Recent Attempts in the Design of Efficient PVC Plasticizers
Chemical and physical properties of PVC formulations containing a wide range of plasticizers have been compared, allowing observance of the improvements in polymer performance in comparison...
Plasticizer - an overview | ScienceDirect Topics
To make PVC flexible at least 15 phr plasticizer is required. Less than this amount induces antiplasticization, and actually increases stiffness. Plasticizers can be used alone or in combination to get the desired properties such as tensile and tear strength or low temperature flexibility.
Eastman Plasticizers for PVC
Admex 523 is a low molecular weight, polymeric plasticizer. It is characterized by a mild ester odor and very light color. It imparts excellent processability to PVC compositions and is compatible with a wide variety of other polymers. Product availability by region: Asia Pacific | Latin America | North America
Polymeric Plasticizers - ScienceDirect
The most efficient plasticizer (greatest reduction in Tg per unit of plasticizer) in this case is the monomeric DOP. Polycaprolactone (see Chapter 22 ), PCL-700, is next, and the two ethylene copolymers are less efficient. Not shown, but still less efficient, is a highly chlorinated polyethylene.
- 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.
- What is a stabilizer in PVC plastic?
- Stabilizers are a key central additive in PVC plastic formulations. Flexible PVC materials are built upon liquid mixed metal soaps that are the most commonly used stabilizers.
- What makes a good plasticizer?
- A good plasticizer must blend uniformly with the PVC matrix, ensuring that it does not phase-separate or lead to inconsistency in the material properties. An effective means to evaluate compatibility is through the analysis of: Solubility: The plasticizer should dissolve in PVC without forming precipitates.
- What are the best value-added PVC plasticizer options?
- Let’s now turn our attention to three value-added PVC plasticizer options that exceed the emerging requirements of REACH and European Union (EU) regulation. VESTINOL® 9 DINP is a very cost-effective, general-purpose plasticizer very useful in soft PVC formulations with a broad processing temperature window.
- What are the characteristics of effective plasticizers?
- Common characteristics of effective plasticizers include: Low viscosity: This trait ensures easier handling and mixing during the compounding process. High molecular weight: Larger molecules can create a more significant distance between PVC chains, leading to improved flexibility.
- 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.
