Flax Fiber Format Tape With Cut Tobacco Cigarette Production Machine
Garniture tape is used for cigarette making machines on format garniture sector to convey cigarette paper with tobacco wrapped in.
We offer aramid tapes and Linen tapes.
Kevlar K119 – higher-elongation, flexible and more fatigue resistant
Kevlar K129 – higher tenacity for ballistic applications
Kevlar AP – 15% higher tensile strength than K-29
Kevlar K-29 – in industrial applications, such as cables, asbestos replacement, brake linings, and body/vehicle armor.
Kevlar K49 – high modulus used in cable and rope products.
Kevlar K100 – colored version of Kevlar
Kevlar XP – lighter weight resin and KM2 plus fiber combination
Kevlar KM2 – enhanced ballistic resistance for armor applications
These interactions have a greater influence on Kevlar than the van der Waals interactions and chain length that typically influence the properties of other synthetic polymers and fibers such as Dyneema.
When Kevlar is spun, the resulting fiber has a tensile strength of about 3,620 MPa, and a relative density of 1.44. The polymer owes its high strength to the many inter-chain bonds. These inter-molecular hydrogen bonds form between the carbonyl groups and NH centers. Additional strength is derived from aromatic stacking interactions between adjacent strands.
For example: enduring 160 °C (320 °F) for 500 hours, reduces strength by about 10%; and enduring 260 °C (500 °F) for 70 hours, reduces strength by about 50%.Kevlar maintains its strength and resilience down to cryogenic temperatures (−196 °C); in fact, it is slightly stronger at low temperatures. At higher temperatures the tensile strength is immediately reduced by about 10–20%, and after some hours the strength progressively reduces further.
