No.

Our products are specialty optical-grade ultra-thick polycarbonate solid sheets with thicknesses ranging from 30-450mm.

In addition, when the demand for a single batch exceeds 50 sheets, the thickness between 20-30mm can be customized.

No.

Our products are special opticalty grade ultra-thick polycarbonate solid sheets, all are transparent or clear.

However, when the demand for a single batch exceeds 100 sheets, the color sheets can be customized, and for the sake of rigor, you need to mail the color sample.

No.

Our products are molded by mold one-piece pouring, and the uniform size specification is 1270*1530mm.

At present, the size specifications cannot be changed or customized, only the thickness can be customized, such as 35mm, 103mm, 200mm, etc.

production time (7 days for normal time, 30 days for busy time) + ocean shipping time (Ningbo port of China to your country).

Single batch order quantity: 

The minimum order quantity is generally 30 sheets, and special thicknesses will be discussed separately.

Quality assurance: 

subject to the sample and the description of this official website, if there is any falsehood, we will bear all costs and return the goods.

No, we only provide optical grade special polycarbonate sheets with size of (30-450mm) * 1270mm * 1530mm.

Because our production is very busy, and the machining of polycarbonate materials is simple and common, we do not do any processing to foreign users.

Of course.

The sample is free, the first mailing fee is paid on delivery or charged, but the mailing fee will be deducted from the order payment, and the subsequent mailing fee is exempted.

Our sample uniform size is 30 * 60 * 60mm, and new users can send up to 5 pieces each time.

Of course. It depends on your own requirements and affordability of costs.

This type of questions has no practical significance, and the applicability is mainly determined by the customer's requirements, not by us, and we will not force it.

The best way is to carefully search and see for yourself around the world.

Initially, the reason why we developed this product ourselves was because there was a large demand for our domestic X project, and we could not find this product in the world.

Yes, you are familiar with polycarbonate materials.

As we all know, polycarbonate is really not suitable for mold pouring production due to the limitations of raw material properties.

Therefore, we must first carry out the technical transformation of chemical grafting adapted to the direction of mold pouring, which must have corresponding professional technology.

This is also one of the two direct reasons why almost no company worldwide currently capable of producing such specialty optical-grade ultra-thick polycarbonate solid sheets.

Our prices are globally uniform and treat all users equally.

Please refer to the Cooperation Policies and Methods for details

Because optical-grade special ultra-thick clear polycarbonate solid sheet has no production precedent, let alone corresponding production equipment.

Therefore, from the pouring mold to the production equipment, we all design it ourselves.

The international tolerance standard for such large thickness materials is ±5%, and our actual thickness tolerance can reach about ±1mm, which is better than international standards.

The functional treatment of UV protection is relatively mature, and this has no technical content.

Our optical-grade ultra-thick special polycarbonate sheets can achieve the actual test result of UV passing rate is close to 0.

Taishang Laojun's alchemy furnace can.

This is a meaningless question, one where you don't understand how polycarbonate materials behave. Such customers have no possibility of closing the deal at all, and it is recommended to read more books.

The temperature of natural gas blue flame is as high as 25000 °C, the temperature of red flame is also as high as 3000 °C, and the temperature of steel melting is generally about 1500 °C. If there is refractory polycarbonate, it may cost much more than gold.

Yes, the functional treatment of polycarbonate flame retardant protection is also relatively mature, which has no technical content.

Our optical-grade ultra-thick special polycarbonate sheets are UL94-V0 grade fire retardant standards, which is also the highest standard in the plastics industry.

Note: This is a completely different concept from burning on a fire.

Yes, the functional treatment of polycarbonate double-sided hardening protection is also relatively mature, which has no technical content. But this function has very important practical significance for the application of polycarbonate sheets.

Double-sided surface hardness grade of our optical-grade ultra-high special polycarbonate sheets: 3-5H (Exceeds most of the hardening levels on the current market)

Yes, double-sided protective film protection, this is the most basic product element. I don't know why so many users ask this question.

Our optical-grade ultra-thick special polycarbonate sheets are protected by PE protective film on both sides, and are not recommended to be removed them before you finish machining.

Increase the scratch resistance function of polycarbonate sheet surface to better serve applications.

As we all know, polycarbonate as the first of the five engineering plastics, although the physical and mechanical properties are excellent, but its surface hardness is not enough to cause easy scratches is its biggest defect, which is also the common problem of all plastics and organic materials.

Of course, engineers are born to solve problems. Attaching a layer of hard matter to its surface by technical means is the perfect solution to the problem.

The surface is smooth horizontally, protected by PE protective film on double sides, and has the same flatness as acrylic (PMMA), glass, and ordinary polycarbonate sheet.

Thanks to the production method of mold pouring, the sheet surface is horizontal.

Sorry, we can't provide it.

Our samples are uniform 30mm and 40mm thickness, the size is 60mm*60mm.

300mm thickness polycarbonate sheet costs a lot and we won't cut the sample. 30mm and 40mm thick samples are already fully representative, and it is not necessary to cut samples for each thickness.

Quite simply, this is determined by the overall superiority of the comprehensive properties of the polycarbonate material, including physical properties, mechanical properties, and easy processing, rather than depending on the superiority of a certain parameter.

It is electrically insulated. (This type of problem has no technical content, and there is a large amount of publicly available information available for inquiry.)

The electrical insulation performance of polycarbonate is determined by its own polymer amorphous polymer structure, and it is a transparent polymer insulation material with excellent electrical performance.

According to the ASTM D150 standard, its dielectric constant is 2.96, and the IEC 60093 standard has a resistivity of 2.17 × 10 ^ 16, with a dielectric strength higher than 16.30KV/mm.

The electrical resistance of polycarbonate is significantly better than that of polyester and aromatic fiber insulation materials, especially in the field of high-end optical transparent insulation materials, which has typical representativeness.
