PVC abc material which is more resistant to high solar temperatures?

PVC is polyvinyl chloride, English name polyvinyl chlorid, is a hydrogen atom in ethylene is replaced by chlorine, and then polymerized into a polymer material, PVC material has non-flammability, high strength, climate resistance and excellent geometric stability, therefore, is one of the most widely used plastic materials, common products include: plates, pipes, soles, toys, doors and windows, wire skins, stationery, etc. The common thin and transparent elasticity on the market is one of them, and it is used for plastic wrap.

Due to the introduction of chlorine, PVC is a plastic that has a certain toxicity and potential harm to human health, so it has been stipulated that it is prohibited to be used as a food packaging material.

The raw material stability of PVC is not strong, does not have the effect of ultraviolet resistance, heat resistance is also poor, and it is easy to degrade under the action of light, heat and oxygen, but this polymer material is irradiated with ultraviolet rays for a short time, and there will be no change. In order to increase the ability to resist ultraviolet rays, oxidation and aging, as well as increase elasticity, various additives are often added in the plastic processing process, such as: heat stabilizers, anti-aging agents, lubricants, plasticizers, colorants, etc.

If it is resistant to ultraviolet rays and aging, it is UPVC, because there is titanium dioxide and anti-ultraviolet additives, but if it is resistant to temperature, it is better ABS, which can reach 70 degrees. If this is the case, use CPVC. Usually, we also sell CPVC pipes and valves to some ship engineering companies and use them on ships.

Of course** not cheap.

All plastic pipes cannot accept direct sunlight.

It is non-flammable, high strength, climatic resistance and excellent geometric stability.

It is non-flammable, high strength, climatic resistance and excellent geometric stability.

Which of them is good for UV resistance, thank you.

PVC has good UV resistance to polyvinyl chloride, English abbreviation PVC is vinyl chloride monomer (referred to as VCM) in peroxide, azo compounds and other initiators; or polymers polymerized under the action of light and heat according to the reaction mechanism of free radical polymerization. The raw material stability of PVC is not strong, it does not have the effect of ultraviolet resistance, and the heat resistance is also poor, and it is easy to degrade under the action of light, heat and oxygen, but this polymer material is irradiated with ultraviolet rays for a short time, and there will be no change.

Is UPVC better than PVC in these aspects?

The frequency of UPVC and PVC pipes is still relatively high, but these two products have their own characteristics. The corrosion resistance of UPVC pipe is more than that of the beam, so it is more common in the use of water pipes, while the cold resistance and heat resistance of PVC pipe are better, so its use is more widely used in drainage systems than slag plums.

1. Polyamide: large molecular weight, non-toxic, good heat resistance, especially heat resistance, not easy to deform, so it can even be used as the manufacture of engine parts. While not comparable to cermet-like materials that can work well at hundreds of degrees Celsius, 200 degrees Celsius is enough to outperform most plastics.

2. PET, polyethylene terephthalate: non-toxic, but monomers, low molecular weight oligomers and side reaction products such as diethylene glycol may remain in the synthesis process, and the melting point of PET in plastics is higher.

3. Polypropylene: Compared with PE products, the heat resistance of PP products is slightly better, and the typical Lock and Lock water cup can reach 110 at a temperature.

4. Polycarbonate: The PC heat separation of polycarbonate products with qualified initial phenol content should reach a high temperature of about 200, which far exceeds the normal use temperature of water cups.

5. PTFE: PTFE has the characteristics of high temperature resistance, can withstand the temperature of 260, and its friction coefficient is very low, so it can be used for lubrication, and has also become an ideal coating for the inner layer of the water pipe that is easy to clean.

Commonly used high-temperature resistant plastics, such as high-temperature nylon, can reach a temperature resistance of 260-290 degrees, and are widely used, so I will not explain much here. The following is an introduction to several relatively rare high-temperature resistant plastics, as well as their simple application characteristics.

This is a comprehensive diagram that describes some of the properties of plastics that are resistant to high temperatures.

Commonly used are polyimide, polyetheretherketone, fluoroplastics, silicone rubber, etc.

What is it used for? How many degrees of high temperature resistance is required?

<> Extended Material: How to Choose High-Temperature Plastics.

1. Consider the heat resistance.

To meet the heat resistance, do not choose too high, too high will cause an increase in cost.

Whenever possible, general-purpose plastics are used to modify. Most of the heat-resistant plastics belong to the special plastics, which are very high, and the general plastics are relatively low.

As much as possible, general-purpose plastics with a large range of heat resistance modification are selected. Plastics with low heat resistance can be modified by the modification method described above, and the heat resistance modification range of different resin varieties is different. Amorphous plastics have a large range of heat resistance modification and can be used as preferred materials.

Common high-temperature plastics: such as polyimide PI, polyetheretherketone PEEK, polyamideimide PAI (also known as Torlon), polybenzimidazole PBI, polyetherimide PEI (also known as ULTEM), polyphenylene sulfide PPS, nylon 46, polysulfone PSU, polyethersulfone PES, PTFE, polycalidene fluoride PVDF and other plastics.

What plastic is the most resistant to high temperature, polybenzimidazole PBI long-term working temperature up to 310, short-term use temperature up to 500, polybenzimidazole PBI is currently the most high-temperature resistant plastic, but it is also the highest in plastics, and it is difficult to process. Therefore, the most heat-resistant plastic is polybenzimidazole PBI.

Secondly, the most high-temperature resistant plastic should be polyimide PI, which can work in an environment of -240 in the long term and 480 in the short term.

Polyamideimide PAI (also known as Torlon) is also a thermoset plastic with a long-term operating temperature of up to 250 °C and excellent low temperature resistance, Torlon has excellent wear and impact resistance at the same time.

The long-term working temperature can reach 160 and the short-term working temperature can reach 260, and the high temperature resistance of the enhanced grade is better.

Polyetherimide PEI, long-term working temperature up to 170 °C, short-term working temperature up to 200 °C.

The long-term working temperature of polyphenylene sulfide PPS can reach 220 °C, and the short-term working temperature can reach 260°C.

PVDF has a long-term working temperature of up to 150 and a short-term working temperature of 160, and has excellent corrosion resistance, as well as high mechanical strength and rigidity.

PTFE has a long-term working temperature of up to 260 degrees and a short-term working temperature of 280 degrees, with excellent corrosion resistance, commonly known as "plastic king". It also has an extremely low coefficient of friction.

The long-term working temperature of polysulfone PSU is 150, and the short-term working temperature can reach 180, and polysulfone PSU also has good comprehensive electrical properties. The performance of PES is similar to that of PSU, with a higher operating temperature, 180 for long-term and 220 for short-term.

Nylon 46, long-term operating temperature up to 135 °C, has excellent toughness and good chemical resistance.

The above is a brief introduction to several commonly used high-temperature plastics, to choose a plastic, only a working temperature guess slag degree parameters are not enough, but also to consider the corrosion resistance, wear resistance, and other factors of the material.
