09. Frequently Asked Questions

Q1: What is the difference between EH-4336 mushroom fastener and ordinary hook & loop tape?

A: EH-4336 is a mushroom-to-mushroom interlocking fastener. Both sides are identical and can lock with each other, no separate hook side and loop side required. It delivers much higher tensile and shear strength than regular textile hook & loop, suitable for vibration-resistant and heavy-load mounting scenarios.

Q2: What sizes are available for EH-4336? Can I get custom shapes?

We offer 4 standard sizes: S, M, L, XL. All standard sizes share the same material, temperature resistance and opening-closing cycles, only differing in contact area and holding capacity. Custom die-cut shapes, special dimensions and color customization are available. Contact sales for MOQ and quotation.

Q3: What is the working temperature range of EH-4336? Is it UV resistant for outdoor use?

The operating temperature range is -40℃ ~ 80℃. It has UV resistance grade 4, works well for outdoor, automotive and exterior mounting. Long-term exposure under intense sunlight is still suggested to do your own field test.

Q4: How many times can EH-4336 be opened and reclosed repeatedly?

The interlocking structure supports more than 1000 open-close cycles without obvious drop of locking force.

Q5: Does it come with adhesive backing? What surface can it stick to?

Standard version is pre-attached with acrylic pressure-sensitive adhesive (PSA). It works best on smooth, clean, rigid surfaces such as metal, plastic, glass and painted panels. Porous, dusty, oily or soft flexible surfaces are not recommended.

Q6: Can I get samples before bulk order? What is your customization process?

Yes, sample testing is supported. Our workflow: Inquiry → Quotation → Sample Confirmation → Mass Production → Shipment → Receipt Confirmation. We only start mass production after your sample approval.
