Product Description 產品描述
NB-4000 series are dynamic or non-dynamic TPNBR & TPVC compounds which are dynamic vulcanized by nitrile rubber and polar resin or non-polar resin. They have excellent oil-resistant (ASTM3# oil, fuel oil, gear oil, brake oil, lubricant oil), anti-ozone, anti-climate, strength and anti-flex properties. They can meet RoHS Standard, and have no heavy metals. NB-4001 is low-halogen flame retardant while NB-4003 is halogen-free. Hardness of NB-4000 series are 75A-40D.
NB-4000系列是丁腈橡膠與級性或非級性樹脂的動態或非動態硫化共混物(TPNBR&TPVC)。有優異的耐油(ASTM3#油，燃油，齒輪油，制動油，潤滑油)，耐臭氧，耐候性；強度，耐曲撓性具優。符合歐盟的RoHS要求，不含重金屬等有害物質。其中4001為低鹵阻燃型，4003無鹵。本系硬度范圍：75A~40D。

The temperature mentioned above is for reference only, and should be modified according to different extrusion machines and screw structures. 以上溫度僅作參考，根據擠出機及螺桿結構的不同，可相應調整。
Dry Condition 干燥條件
No need for drying in normal environment. If the compound was affected with damp, dry it in 90℃ conditions for 2-3 hours, or in 70-80℃conditions for 3-4 hours. Keep the moisture content of the compound smaller than 0.1wt%.
一般不需干燥。如受潮，在90℃條件下干燥2-3小時，或在70-80℃條件下干燥3-4小時，保持樹脂含水量小于0.1wt%后再使用。
