Technical & Standard
PVC heat shrink tubing technical standards (abstract)
|
1、Range
This standard applies to 85 ℃ and 105 ℃ series PVC heat shrink tubing.
|
|
2、 Technical Parameters
2.1 Shrinkage ratio
Calculation formula： S=[(Lo-L)/Lo]×100%
ΔS=(max-Lmin/Lo)×100%
Type： S---Shrinkage, including longitudinal and lateral shrinkage
ΔS---Shrinkage tolerance
Lo---The length or diameter before heat shrinkage
L---The length or diameter of the heat shrink
Lmax ---The maximum length or diameter of the specimen after heat shrinkage
Lmin ---The minimum length or diameter of the specimen after heat shrinkage

1, Φ5, Φ6, Φ8, Φ10 four specifications divided into large, medium and small three different diameter. Φ16 points large and small two different diameter.
2, the specifications of a column Φ2.0 ~ Φ80 for the package material shell size, Φ85 above the size of the size of the set diameter.
3, long conversion value is for reference only. Customers have special specifications, size, technical requirements, the two sides can be agreed.
