What’s PVDC fiber “Saran™”
PVDC fiber "Saran™"
Saran™ fiber is manufactured by the melt spinning of Polyvinylidene chloride copolymer. Its performances stand out in the many applications from consumer products to industrial applications.
Features of "Saran™"
1. Excellent Flame Resisting
Saran™ fiber is inherently self-extinguishing, making the addition of flame-retardants unnecessary. This means consistent, uniform flame-retardant properties, free from variations which occur during flame-retardant compounding. Saran™ fiber plays an important role in applications requiring high flame-retardant properties.
2. Superior Chemical Resistance
Saran™ fiber is resistant to acids and alkalis, and is insoluble in oils and most organic solvents, making it suitable for use in applications involving exposure to chemicals. (Note that it is soluble in some solvents such as tetrahydrofuran and cyclohexanone.)
3. Fast Color and Excellent Gloss
Because pigment is added before fiber spinning, Saran™ fiber has vivid color with excellent colorfastness, retaining its translucence and luster even with exposure to sunlight and weather.
4. Extremely Low Moisture Regain
With a moisture regain of less than 0.1%, its physical properties are almost completely unaffected by absorbed water. This makes Saran™ fiber well-suited for use underwater, outdoors exposed to rain, and even in demanding fields such as wastewater treatment and undersea applications.
5. Freedom from Mold, Bacteria Damage
Saran™ fiber is nearly impervious to mold, bacteria, and insects, so its properties are not degraded in highly humid environments or mud. Saran™ fiber is often used underground and in contactor with sludge.
6. High Elastic Recovery
With a high elastic recovery, Saran™ fiber resists, Saran™ fiber resists wrinkling and creasing. This enables the production of a 3-dimensional fabric using Saran™ monofilament.
