防水气密拉链选型指南

选型核心看四件事：防水等级（IPX6-IPX8）、规格（#5/#8/#10）、材料（TPU/PEVA/硅胶/尼龙）和定制参数（长度/幅宽/颜色/拉头）。先确定应用场景，再按密封要求从高到低逐项匹配，即可快速锁定型号。

Selection comes down to four things: waterproof rating (IPX6-IPX8), size (#5/#8/#10), material (TPU/PEVA/silicone/nylon), and customization (length/width/color/slider). Identify your application first, then match sealing needs from high to low to narrow down the model.

第一步：确定防水等级

Step 1: Determine the waterproof rating

等级	防护能力	典型应用	YILON 对应产品
IPX6	防强力喷水	雨具、防水袋、普通防水服	PEVA / TPU 防水拉链
IPX7	短时浸水（1m、30分钟）	涉水装备、浮潜服、水上运动	#5/#8 TPU 水密拉链
IPX8	持续浸水（>1m，按约定）	干式潜水服、深海作业服、军工/医疗保压	#8/#10 TPU 气密拉链

Rating	Protection	Typical uses	YILON products
IPX6	Powerful water jets	Rainwear, dry bags, standard waterproof wear	PEVA / TPU waterproof zippers
IPX7	Temporary immersion (1m, 30 min)	Wading gear, snorkeling, water sports	#5/#8 TPU watertight zippers
IPX8	Continuous immersion (>1m, by agreement)	Drysuits, deep-sea workwear, military/medical pressure sealing	#8/#10 TPU airtight zippers

第二步：选择规格

Step 2: Choose the size

规格	齿链宽参考	适用
#5	约 5mm	轻量化服装、防水袋、一般户外装备
#8	约 8mm	防护服、潜水服、充气装备
#10	约 10mm	重型工业、军工、快速卷帘门、高压保压设备

Size	Approx. chain width	Applications
#5	~5mm	Lightweight garments, dry bags, general outdoor gear
#8	~8mm	Protective suits, drysuits, inflatable products
#10	~10mm	Heavy industry, military, rapid roller doors, high-pressure sealing

第三步：选择材料

Step 3: Choose the material

TPU：综合性能最佳——弹性、耐磨、耐水解、耐温 -30~70°C，气密首选；
TPU: best all-round performance — elasticity, abrasion and hydrolysis resistance, -30 to 70°C range, first choice for airtight sealing.
PEVA：轻量、低成本，适合日常防水；
PEVA: lightweight and low-cost, for everyday waterproofing.
硅橡胶：高柔韧、耐候，用于潜水服封套等；
Silicone rubber: highly flexible and weather-resistant, used for drysuit envelopes.
尼龙：柔软、适合水密场景，高压气密不如 TPU 一体成型。
Nylon: soft, good for watertight uses, but less effective than one-piece TPU for high-pressure airtight sealing.

第四步：确认定制参数（12 项）

Step 4: Confirm the 12 customization parameters

应用场景、长度范围、开口长度、规格/幅宽、颜色、拉头样式、端部结构、材料、防水等级、耐油要求、测试条件、数量。

Application, length range, opening length, size/tape width, color, slider style, end structure, material, waterproof rating, oil-resistance requirement, test conditions, and quantity.
