TM-4
is 4-layer fabric, layers are bonded by linen weaving repeating.
T-P is twill weave 2x2 fabric. T-1 - twill weave
2x2. T-2 - linen weave 1x1
TEMPERATURE OF CARBONIZATION: 2200°C.
Fabric is on paper roll (60 mm diameter min).
Roll length is 700±30 mm. In every roll only 1 (one) piece of fabric.
Fabric weight: 5kg min; 3 kg weight is allowed for 10% of pieces in the
lot.
Roll of fabric is wrapped into polyethylene (PE) film and then packed
into cardboard box.
