Methods to Enhance PVC Properties – Role of Additives.
PVC resin obtained from polymerization is extremely unstable due to its low thermal stability & high melt viscosity. It needs to be modified before processing into finished products. Its properties can be enhanced/modified by adding several additives, such as heat stabilizers, UV stabilizers, plasticizers, impact modifiers, fillers, flame retardants, pigments, etc. Selection of these additives to enhance polymer’s properties is dependent on end application requirement. For example: 1.Plasticizers (Phthalates, Adipates, Trimellitate, etc.) are used as softening agents to enhance rheological as well mechanical performance (toughness, strength) of vinyl products by raising the temperature. Factors that affect the selection of plasticizers for vinyl polymer are:Polymer compatibili... -
A polylactic acid 3D printed chair that subverts your imagination.
In recent years, 3D printing technology can be seen in various industrial fields, such as clothing, automobiles, construction, food, etc., can all use 3D printing technology.

Analysis on the Changes of PE Downstream Consumption Varieties in the Future.
At present, the consumption volume of polyethylene in my country is large, and the classification of downstream varieties is complicated and mainly sold directly to plastic product manufacturers. It belongs to the partial end product in the downstream industry chain of ethylene. Coupled with the impact of the regional concentration of domestic consumption, the regional supply and demand gap is not balanced. With the concentrated expansion of production capacity of my country’s polyethylene upstream production enterprises in recent years, the supply side has increased significantly. At the same time, due to the continuous improvement of residents’ production and living standards, the demand for them has steadily increased in recent years. However, since the second half of 202... -
What Are The Different Types of Polypropylene?
There are two main types of polypropylene available: homopolymers and copolymers. The copolymers are further divided into block copolymers and random copolymers. Each category fits certain applications better than the others. Polypropylene is often called the “steel” of the plastic industry because of the various ways in which it can be modified or customized to best serve a particular purpose. This is usually achieved by introducing special additives to it or by manufacturing it in a very particular way. This adaptability is a vital property. Homopolymer polypropylene is a general-purpose grade. You can think of this like the default state of the polypropylene material. Block copolymer polypropylene has co-monomer units arranged in blocks (that is, in a regular pattern) and contain any... -
What are the Characteristics of Polyvinyl Chloride (PVC)?
Some of the most significant properties of Polyvinyl Chloride (PVC) are: Density: PVC is very dense compared to most plastics (specific gravity around 1.4) Economics: PVC is readily available and cheap. Hardness: Rigid PVC ranks well for hardness and durability. Strength: Rigid PVC has excellent tensile strength. Polyvinyl Chloride is a “thermoplastic” (as opposed to “thermoset”) material, which has to do with the way the plastic responds to heat. Thermoplastic materials become liquid at their melting point (a range for PVC between the very low 100 degrees Celsius and higher values like 260 degrees Celsius depending on the additives). A primary useful attribute about thermoplastics is that they can be heated to their melting point, cooled, and reheated again wi... -
