• Place orders in lots of 10 pieces.
• Contact us for long, thick-walled, or colored products.
• Contact us for conductive types.
• Store in a cool, dark place (30°C or below) to maintain the inner diameter before shrinkage.
• The inner diameter after shrinkage is measured after heating at 200°C for 10 minutes and is not a guaranteed value.
• P type has higher heat resistance than F type.
• Ultrafine tube of small diameters other than the above standard specifications can also be manufactured, so consult with us.
Since EIT stretches slightly in the longitudinal direction when shrinking, it can be installed without wrinkles by pulling the unshrunk side of the tube while processing when covering a long product.
Contact us for the applicable size.
Thick-walled and long products are also available.
