Different coloring methods for plastics

In our daily life, we are exposed to a variety of plastic products , and these plastic products are various in color, bright and bright, which is inseparable from the dyeing technology of plastic products.

Plastic dyed thermoplastic materials are mostly transparent or milky white, while precision plastic parts often impose various requirements on color. Parts in optical instruments require black to prevent light leakage and stray light removal. Appearance parts are often used according to design needs. s color. Therefore, before the processing of plastic products, it is necessary to carry out dyeing, that is, mixing different proportions of dyes in plastics. The dyeing methods of thermoplastics are as follows:

Plastic product manufacturers talk about plastic dyeing methods in three categories: toner, color masterbatch, pumping, each type of dyeing method has its advantages and disadvantages, which one to choose, depending on the specific circumstances.

First, the toner

Advantages of toner: 1, cheap, affordable. 2, the proofing time is short, the production is fast, and the desired color can be quickly completed. 3. Easy transportation. 4. Suitable for a small variety of products.

Disadvantages of toner: 1. When the toner is stirred, the pollution is large, and the mixing drum is not easy to clean. 2, different raw materials, different brands or batch numbers and operating conditions are different, machine and mold different operating temperature differences, different ways, will produce color difference. 3. Poor dispersion.

Second, the color master

Color master benefits: 1, the color is more stable. 2, will not pollute the environment. 3, the price is moderate, the inventory is small. 4. Good dispersion. 5, suitable for central feeding system, long-term orders.

Color master defects: 1, must have a certain amount of production, the proportion of addition is generally 2--4%. 2, must be evenly distributed to prevent static electricity or otherwise produce chromatic aberration.

Third, pumping

Advantages of pumping: 1. The color is stable, and the impurities of raw materials are eliminated. 2, the operation is simple, no need to stir the material, can greatly increase the production capacity. 3. Do not pollute the environment. 4, can be directly produced.

Disadvantages of pumping: 1. Cost is higher than color masterbatch and toner. 2. During the pumping process, the physical properties of the raw materials may be reduced. 3. Large inventory and high transportation costs.

PC plastic,full name Polycarbonate.

PC plastic is a kind of excellent comprehensive performance engineering plastics.It has excellent physical, mechanical, electrical, and thermal properties,so it's known as the "king of the transparent plastic'

Classification:

Anti - static PC SHEET, conductive PC SHEET,fireproof PC SHEET,PC fiber - resistant, PC GF SHEET, PC+ABS SHEET,anti-ultraviolet ray resistance PC, food grade PC, anti - chemical PC.

Advantages:

1,Light weight

2,Impact resistance

3,Excellent physical, mechanical, electrical and thermal properties

4,Ultraviolet resistance

Disadvantages:

Polycarbonate is not resistant to ultraviolet light, no resistance to alkali, resistance to hydrolysis stability is not high, is the main performance defect is sensitive to the gap, resistance to organic chemistry, scratch resistance is poorer, long-term exposure to ultraviolet light yellow, are vulnerable to the erosion of some organic solvents.

Applications:

1. Dust-free room spacer

2. Equipment shield and test fixtures;

3. Commercial Building Lighting;

4. Soundproof walls;

5. Greenhouse;

6. Components for medical and pharmaceutical devices;

7. Face shields;

8. Skylights, etc

Modified use:

The purpose of the modified PC Plastic is to toughen, improve the processing performance, reduce the residual deformation, and increase the flame retardancy, etc.

PC/ABS can improve bending modulus, heat resistance and plating performance.

PC/PET and PBT can improve drug resistance and solvent resistance.

PC/PMMA added plexiglass to enhance the appearance of pearlescent color.

PC/PA and HIPS can improve impact toughness and surface finish.

PC/HDPE can improve water resistance, aging resistance, weather resistance and LDPE.

The PC Plastic USES fiberglass or carbon fiber to enhance modification and improve mechanical strength.

The flame retardant grade PC Plastic can be made with bromine flame retardant and antimony trioxide.

Other and polysulfone, aromatic polycarbonate, polyvinyl formaldehyde, polypropylene, polystyrene can be modified to achieve the balance between economy and performance.

Combustion characteristics:

Combustion condition: easy, softening foaming

Flame status: small amount of black smoke

After the fire: out of the fire

Bouquet: no special taste

Specification: the thickness of PC Plastic sheet material can be produced from 0.3mm to 1.9mm, the normal width is 600mm, the width cannot exceed 1200mm, the length is not limited.
The thickness of plate can be produced from 2mm to 180mm, the usual specification of 2-10mm is 1000mm* 2000mm, and the commonly used specification of 10-180mm is 600*1200 mm. PC Plastic sheet can also be customized according to requirements, and the width cannot exceed 1200mm, and the length is not limited.and The diameter of the PC Plastic rod can be produced from 2mm to 250mm, the length is 1 meter, and it can be ordered to be more than 3 meters in length.

Color: Black and clear, can also be made another color, and the color order is 500KG.

Modified varieties:PC Plastic can be added to the Glass Fiber, copper powder, and molybdenum disulfide enhancement plate according to customer's requirements.
Add antistatic agent to the permanent plate, the volume resistance value of 10 to the 6 to 9 power.
Add flame retardant to the flame retardant board from UL 94v-0 to HB combustion grade, and other modification requirements are required to customize various additional properties according to the actual use of the customer.

Product certification: most environmental certification reports and safety reports for raw materials, such as SGS report, CTI report, UL report, MSDS safety information, etc.
