Heat Insulation Nylon Strips Used in Windows
Shape I, shape C, shape T, shape CT and shape HK is the most common shape, we can also according to customer requirements or drawings to customize other special shape.
1.Effectively increased thermal in the system property insulation.
2.Reduces condensation on the window.
3.Sound insulated.
4.Improve comfort and living condition.
5.Possible double color coatings provide better aesthetic effect.
6.Various shapes will be designed for the customer's requirements.
7.The working temperature of the thermal insulation strip is 220°C, Melting Point reaches to 246°C. This enables coating process after assembly of composite profiles.
8.High corrosion-resistance, weather-resistance, heat-resistance, alkali-resistance and long life of usage.
9.linear thermal dilation coefficient almost identical to that of aluminium profiles.

1.Sample water content less than 0.2% by weight.
2.Norm laboratory condition:(23±2)ºC and (50±10)% relative humidity.
3.The specifications marked with "a" only applies to I-shape strip otherwise, the specifications concluded between supplier and buyer through consultation, shall be written in contract or purchase order.
The strips will be stored in the ventilated and dry environment, horizontally placed, paying attention to waterproof, keeping away from the heat source, avoiding heavy pressure and the contact with acid, alkali as well as organic solvent.
We have the production capacity of 100000 meters per day. For common specifications, we have molds, and will be shipped in 15-20 working days after receiving the deposit.
1.What is the minimum order quantity for your rubber products?
We didn’t set the minimum order quantity,1~10pcs some client has ordered
2.lf we can get sample of rubber product from you?
Of course, you can. Feel free to contact me about it if you need it.
3. Do we need to charge for customizing our own products?And if it is necessary to make tooling?
if we have the same or similar rubber part, at the same time, you satisfy it.
Nell, you don’t need to open tooling.
New rubber part, you will charge tooling according to the cost of tooling.n additionalif the cost of tooling is more than 1000 USD, we willreturn all of them to you in the future when purchasing orderquantity reach certain quantity our company rule.
4. How long you will get sample of rubber part?
Jsually it is up to complexity degree of rubber part. Usually it take 7 to 10work days.
5. How many your company product rubber parts?
it is up to the size of tooling and the quantity of cavity of tooling.lf rubber part is more complicate and much bigger, well maybe justnake few, but if rubber part is small and simple, the quantity is more than 200,000pcs.
6.Silicone part meet environment standard?
Dur silicone part are allhigh grade 100% pure silicone material. We can offer you certification ROHS and $GS, FDA. Many of ourproducts are exported to European and American countries., Such as: Straw, rubber diaphragm, food mechanical rubber, etc.
