关于快递
江浙地区200kg左右主要发速通物流或者安能物流，500kg以上的发物流托运。
关于色差
产品图片均为100%实物拍摄，但是由于显示器的差别，可能会存在或多或少的色差。我们在处理图片
时，会尽量接近宝贝的真实颜色。但是有些色差很难避免。希望亲们谅解！
关于重量
因为我们的产品不定长定重，我们在打包的时候尽量做到差不多重量的放在一起，小卷（小于0.3kg/
只的做废丝处理）是单独打包的。希望各位老板下单前了解清楚再下单。
关于退换货
退货条件：外包装完整，且不影响二次销售。一旦拆封无法复原商品不可退货（质量问题除外）。若
交易已完成，发现质量问题，请在交易完成后15天内进行退货申请。无可退换货特殊说明：无质量问题
且外包装已拆无法复原，影响二次销售。商品的图片及信息仅供参考。因拍摄灯光及不同显示器色差等
问题可能造成商品图片与实物有细微色差。
退换货费用说明：如果是买家原因退货，由买家自行承担退货费用。如果是单丝质量问题、描述不符而
导致退货，退货费用则应由我司承担。
Polyvinylidene fluoride (PVDF):
White powder crystalline polymer. The density is 1.75-1.78g/cm3. The glass transition
temperature is - 39 ℃, the embrittlement temperature is - 62 ℃, the melting point is 170
℃, the thermal decomposition temperature is about 350 ℃, and the long-term use
temperature is - 40 ~ 150 ℃. It can be formed by general thermoplastic processing method.
Its outstanding characteristics are high mechanical strength and good radiation resistance.
It has good chemical stability and is not corroded by acid, alkali, strong oxidant and
halogen at room temperature. A few chemicals such as fuming sulfuric acid, strong alkali,
ketone and ether cotton can make them swell or partially dissolve. Strong polar organic
solvents such as dimethylacetamide and dimethylsulfoxide can make them dissolve into
colloidal solution.
1. PVDF has excellent chemical corrosion resistance, high temperature color and oxidation
resistance.
2. PVDF has excellent wear resistance, flexibility, high tensile strength and impact
strength.
3. PVDF has excellent resistance to ultraviolet and high energy radiation.
4. PVDF has poor hydrophilicity.
5. Fluorinated resin (commonly known as thermoplastic Teflon).
6. Good heat resistance and high dielectric strength
We can provide free technical support. If you want to buy, you can send samples for free
and provide processing for samples.
About express
Jiangsu and Zhejiang regions mainly develop express logistics or energy logistics about
200kg, and more than 500kg are consigned.
On chromatic aberration
The product pictures are all taken in 100% real objects, but due to the difference of the
display, there may be more or less color difference. When we deal with pictures, we try to
be close to the real color of the baby. But some color differences are hard to avoid. I
hope you understand!
About weight
Because our products vary in length and weight, we try to put them together as much as
possible when packing. Small rolls (less than 0.3KG / piece for waste wire treatment) are
packed separately. I hope you all know before you place an order.
About return and exchange
Return conditions: the outer package is complete and does not affect the secondary sales.
Once unsealed, goods that cannot be recovered cannot be returned (except for quality
problems). If the transaction has been completed and quality problems are found, please
apply for return within 15 days after the completion of the transaction. No special
instructions for returnable and exchangeable goods: there is no quality problem and the
outer package has been disassembled and cannot be recovered, which affects the secondary
sales. Pictures and information of the goods are for reference only. Due to problems such
as shooting light and color difference of different displays, there may be slight color
difference between commodity pictures and real objects.
Description of return and exchange fee: if the buyer returns the goods for the reason, the
buyer shall bear the return fee. If it is the quality problem of monofilament and the
description is inconsistent that leads to the return, the return cost shall be borne by our
company.
