What is the proportion of pure monomer resin used in plastics

Difference Between Resin and Plastic:

1. Plastic: refers to the material that can flow and form in the process of processing with resin (or direct polymerization with monomer in the processing process) as the main component, and additives such as plasticizers, fillers, lubricants, colorants and other auxiliary components in the processing process, and can also be said to be plasticity materials and products with resin as the main raw material. Plastic generally refers to finished products, such as plastic cups, plastic bowls, etc.

2. Resin: refers to raw materials, such as polyethylene resin, polypropylene resin, polyester resin, etc., but in general, the two terms plastic and resin can be used universally. So, it can be said that plastic is resin, and resin is plastic.

It can be seen that resin is one of the raw materials of plastics, and plastics are the finished products of resins. In other words, what is not molded is resin, and after molding, it is plastic.

This question is not very clear, UV aging requirements are the requirements of the product use environment and plastic parts, so these must be clear, and the choice of plastic materials is not the same as adding UV.

The first part, it depends on what variety.

The addition of plastic fillers depends entirely on the cost control and quality requirements of the manufacturer, and there must be relevant process specifications for standard control, not as much as you want to add.

There are many types of fillers used in plastic resins, and the more commonly used are solid materials such as granular, flake, and fibrous, which are mainly used to increase the volume or quality of plastic products to reduce the manufacturing cost of plastic products. In addition, there are some special functional fillers, which are added to improve the physical properties, mechanical properties and functionality of the product, such as electrical conductivity, thermal conductivity, flame retardant, lubrication, thermal insulation, insulation, shock absorption, sound insulation and other properties. The following conditions should be paid attention to when selecting fillers.

1) The resin raw material is filled with human filler, which does not react chemically with resin and additives, and has a small ability to absorb plasticizers. (2) It does not affect the performance of resin and the quality of molded products. (3) It has appropriate fineness, can be evenly distributed in the resin, and does not contain crystal water.

4) The amount of filler should be appropriate, so that there can be no problems with the product.

This depends on the product and the application.

Look at what products are made, generally available in PVC resin: 50 to 100 copies (per 100 parts of resin) View the original post

Because plastic products should be matched with color, plastic raw materials can be divided into: granulated materials, toners, color materials, and recently appeared liquid coloring in plastic raw materials.

Granule raw material is to have mixed the pigment into the raw material, each plastic material has been colored, so the color of the product is stable and uniform, toner and color seed material is to mix the color or toner to make it achieve the specified color.

Acrylic pigment belongs to synthetic polymeric pigments, invented in the 50s of the 20th century, is made of pigment powder and acrylic latex. Acrylic latex is also known as acrylic resin polymerized latex. There are many types of acrylic resins, such as methacrylic resins, and there are also many types of acrylic paints.

Professional questions to find professional manufacturers, Chenmei pigment masterbatch manufacturers mainly produce plastic pigments and masterbatches, can help you answer professional and technical questions. 158/168/96316.

There are more common varieties such as yellow 12 14 83, orange 13 34, red 53 48 254, blue, green, purple, etc., and of course there are many more, which can be matched with various colors of Pantong Raul. The first pigment is also based on the structural properties of the pigment from low to high, high-grade pigments have high temperature resistance, good light resistance, and good weather resistance; Economical pigments, **affordable, high tinting strength. o( o Ha For more professional answers, please contact Shanghai Shengqi International ******, product service:

Commonly used types of plastics.

ABS: commonly known as engineering plastics, can be used for connectors, seat backs, seat boards, it is the main raw material for electroplating (water plating) in plastics.

PP: Common name polypropylene, used for five-star feet, handrails, foot pads and connectors with low strength requirements. Disadvantages: poor wear resistance, low surface hardness.

PVC: commonly known as polyvinyl chloride, mainly used for edge banding and insertion conditions. It is suitable for extrusion molding, and at the same time, PVC material is a non-combustible material in plastic parts, and the temperature stability of processing and molding is poor, especially the stability of color is not good.

PU: common name polyurethane. It is mainly used for handrail (foam) accessories.

POM: Common name Saigang. It is mainly used for wear-resistant parts such as foot pads, casters, door hinges, hinges, etc. The performance is wear-resistant and pressure-resistant, but the dimensional stability is poor.

PA: Common name nylon. It is mainly used as foot pads, five-star claws, casters and other wear-resistant places with high life requirements.

Features: wear-resistant, pressure-resistant, high-strength indoor service life, individual models such as PA66 high temperature resistance up to 2200, the disadvantage is that it is easy to change the performance in the sun, easy to break, and poor weather resistance.

PMMA: Plexiglass (commonly known as acrylic). There are five kinds of transparent materials in plastic, and PMMA is one of the most transparent, the workpiece has an acetic acid smell when cutting, it is easy to process and deform, and it can be shaped and bent by soaking it in boiling water.

Disadvantages: the surface is easy to scratch, the hardness is low, it is easy to crack when bending, ** more than 20% higher than ABS.

PC: commonly known as polycarbonate. This variety is also a transparent material, with high surface hardness, scratch resistance, impact resistance, high strength, and good weather resistance (that is, it is not afraid of sunlight).

The screen partition and sunlight panel in the furniture are hollow extruded from this material. Features: High cost, about 40% higher than PMMA.

Synthetic resin is a type of plastic.

According to the different uses, PVC plasticole plastics are often divided into: non-plasticized PVC, plasticizer content is 0; Rigid PVC, plasticizer content less than 10%; semi-rigid PVC, plasticizer content of 10-30%; soft PVC, plasticizer content of 30-70%; Polyvinyl chloride paste plastic, plasticizer content is more than 80%.

The plasticizer content of soft PVC refers to PVC products with more than 25 parts.

The specific gravity can not only be for the plasticizer, although the plasticizer and PVC account for a large proportion (according to the product and the formula is different), but the specific gravity is calculated according to the proportion of the whole formula contained in the proportion of each raw material, the proportion is significant, the first to analyze the raw materials of the formula, can not simply say that the plasticizer is the cause or PVC reason.

Generally, the content of plasticizer is more than 30% of the content of PVC, and it is considered that this material is soft PVC, which is also what we call 30 parts or 30PHR
