BioThane, Beta 520, Super Heavy

The BioThane® Beta 520 Super Heavy product is a PVC coated polyester webbing with a matte finish and 'leather' embossed grain surface. The feel is soft and flexible. BioThane webbing is waterproof, durable, UV resistant, weldable, and easy to clean. A great leather alternative for pet products, dog collars, leashes, belts, leads, strapping, equine saddlery tack, and more.

Type: Beta 520 Super Heavy

Beta 520 Super Heavy Specs:

  • Thickness: Super Heavy = 4.0mm - 0.15" inch - (10oz)
  • Surface Finish: Embossed leather grain texture with a matte finish
  • Material: Polyester webbing interior (B10) with PVC exterior coating
  • Temper (Stiffness): Semi-Soft - Pliable
  • Tape Color: Multiple Choices
  • Webbing Widths: 1/2", 5/8", 3/4", 1"
  • Break Strength: 1,000 lbs per square inch (453 kgs)

Lengths:

  • By the foot - continuous length
    • For example, if you order a quantity of 9, you will get 9 continuous feet.
    • There are up to 2 splices in a roll of 100 feet. Therefore, we only guarantee continuous lengths of up to 10 feet, meaning if you order a quantity of 17 of the 1-foot (continuous length), it is possible you will receive a 10 foot length and a 7 foot length.
  • 25 Foot Roll
  • 100 Foot Roll
    • In a 100' roll BioThane does not guarantee 100 continuous feet. There may be up to 2 splices (3 pieces) in a roll of 100. But no piece will be shorter than 10 feet.

 Beta 520 Standard vs Super Heavy:

  • The only difference between standard and super heavy is the PVC coating thickness. Super heavy has a total thickness of 4.0mm (10oz) compared to standards 2.5mm (6oz) thickness. Break strength is the same for both (1,000 lbs per square inch) as the strength comes from the polyester webbing inside the PVC coating, and this webbing is the same for standard and super heavy.

 FAQ:

  • Can you sew through BioThane?
    • Absolutely! For sewing tips and how to's please click here.
  • Can you use rivets on BioThane?
    • Yes. Punching holes or using self-piercing tubular rivets is great on BioThane products.
  • Can you heat and seal BioThane?
    • Yes, cutting and heating BioThane is possible. When you cut the webbing it is not necessary to seal the ends. The polyester webbing will not absorb the water. However, for aesthetic reasons or applications where welding the product is required you certainly can. Please click here to view the safety sheet for heating as it is toxic and your area should be well ventilated.
  • Can you paint BioThane edges?
  • How do you clean BioThane?
    • Warm water and soap will work well. You also can dab the BioThane with a small amount of rubbing alcohol.

Muzzled pup fix

So happy I found you guys! My dog has to wear muzzles that I’m spending a small fortune on and he keeps getting them off and chewing up the straps. Much cheaper to order this way and cut and fix the straps myself rather than ordering from the muzzle maker. Thank you for helping keep my boy and other...

BioThane for 25 ft. Leash

This is my first experience with BioThane. My impression is that it’s about the greatest stuff on the planet. Tough, lite, waterproof … all the things you want if you’re making a long leash. The bright orange is great for visibility.
