新帝克工廠定做PVDF單絲海釣紗布用

 聚偏氟乙烯（PVDF）：

  白色粉末狀結晶性聚合物。密度1.75-1.78g/cm3。玻璃化轉變溫度-39℃，脆化溫度-62℃，熔點170℃， 熱分解溫度350℃左右，長期使用溫度－40～150℃。可用一般熱塑性塑料加工方法成型。其突出特點是機械強度高，耐輻照性好。具有良好的化學穩定性，在室溫下不被酸、堿、強氧化劑和鹵素所腐蝕，發煙硫酸、強堿、酮、醚綿少數化學藥品能使其溶脹或部分溶解，二甲基乙酰胺和二甲基亞砜等強極性有機溶劑能使其溶解成膠體狀溶液。

1、PVDF具有優良的耐化學腐蝕性、優良的耐高溫色變性和耐氧化性。

2、PVDF具有優良的耐磨性、柔韌性、很高的抗漲強度和耐沖擊性強度。

3、PVDF具有優良的耐紫外線和高能輻射性。

4、PVDF親水性較差。

5、可射出及押出之氟化樹脂（俗稱熱可塑性鐵氟龍）。

6、耐熱性佳并有高介電強度

關于快遞

  江浙地區200kg左右主要發速通物流或者安能物流，500kg以上的發物流托運。            

關于色差

  產品圖片均為100%實物拍攝，但是由于顯示器的差別，可能會存在或多或少的色差。我們在處理圖片時，會盡量接近寶貝的真實顏色。但是有些色差很難避免。希望親們諒解！          

關于重量

  因為我們的產品不定長定重，我們在打包的時候盡量做到差不多重量的放在一起，小卷（小于0.3kg/只的做廢絲處理）是單獨打包的。希望各位老板下單前了解清楚再下單。            

關于退換貨

  退貨條件：外包裝完整，且不影響二次銷售。一旦拆封無法復原商品不可退貨（質量問題除外）。若交易已完成，發現質量問題，請在交易完成后15天內進行退貨申請。無可退換貨特殊說明：無質量問題且外包裝已拆無法復原，影響二次銷售。商品的圖片及信息僅供參考。因拍攝燈光及不同顯示器色差等問題可能造成商品圖片與實物有細微色差。

退換貨費用說明：如果是買家原因退貨，由買家自行承擔退貨費用。如果是單絲質量問題、描述不符而導致退貨，退貨費用則應由我司承擔。

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.
