1. Rubber
Peyton Scow

2. History 1820- Threads and fabrics
1839-Vulcanizing rubber was developed by Charles Goodyear
1876- British smuggled out rubber-tree seeds from Amazonia
Bred to be resistant and sent to Asia plantations in Malaysia, Ceylon and Singapore.
1920s- Henry Ford planted 70 million rubber tree seedlings
1940s- Synthetic

3. What is it? Latex Synthetic Brazilian rubber-tree (Hevea Brasiliensis)
Dandilions
200 plants
Synthetic
Emulsion styrene-butadiene rubber (E-SBR)
Neoprene

4. neoprene Polychloroprene Acetylene and hydrochloric acid
Protective glove, apparel, wetsuits, technical hoses and belts, seals and membranes, and coating for wires.
Resists acid, alkali, alcohol, oil and solvents

5. Elastomers Natural or synthetic
Stretch repeatedly at least twice length
Immediately return back to normal length
Rubber is the oldest

6. How is it made? V cut in tree Filtered Washed
Reacted with acid to make the particles coagulate
Pressed into sheets
Dried
Mastication- machines break up raw rubber using mechanical rollers and presses to make it softer, easier to work, and more sticky.
Chemicals added
Calendering- Shaped by roller
Extrusion- Squeezed through holes to make hollow tubes
Vulcanized- sulfur is added and heated to 280°F

7. How is it made? Coated Dried Rolled Weaved Treated
Expands 2 or 3 times
Take out guild threads by carbonizing
Cut

8. Build Round or rectangular cross section Excellent elongation
Excellent recovery
Low strength
Low dye acceptance
Sensitive to aging sunlight, body oil, perspiration, heat, chlorine bleach, and solvents
Resists alkalis

9. Characteristics Non air-wicking Strength Flexibility
Low noise and vibration
Heat and pressure resistance
Impermeable
Flame resistant

10. Challenges Grommets are used to vent unbreathable membranes
Hard to create buttonholes
Zipper, Velcro, and snap closures
Pinholes and tailor tacks will create permanent holes.
Cannot be pressed
Facings and hems must be under-stitched, glued, or heat welded

11. uses Hearts Washing machines Hoses Boots Tires Boats Electrical cables
