What kind of rubber material can reach 700% elongation rate?
Natural glue can be, in general, is about 500, but to high elongation can also, the formula adjustment can meet the requirements. Natural rubber maximum elongation, I have done more than 1000%. It's not a problem. Don't use the best glue, either.
Thermoplastic elastomer, some types of elongation is far more than 700%, SIS (styrene / isoprene block copolymer), elongation is easy to 1000%, tensile fracture strength is generally more than 10MPa.
