KVIS 30

KVIS 30 is the trade name of Kothari’s slightly higher molecular weight polyisobutylene, ranging from 1250 to 1350. KVIS 30 is widely used by our customers as a cling additive in stretch / cling film manufacturing (either incorporated directly into film extrusion or through a PIB masterbatch) and sealants.

Sealants and Caulks

Polybutene addition attributes to modification of properties like  Tack, Softness, Bond strength, Cohesive strength and Water resistance of adhesives

KVIS polyisobutylenes are most widely used in sealants and putty formulations as an effective replacement for the drying oils.

The polybutene can impart the following properties to the sealants

  •  Permanence
  •  Improved adhesion and cohesion and
  •  Aging
  •  Less shrinkage
  •  Lower oil-to-filler ratios

 

KVIS polyisobutylenes act as a plasticizer and it add tack to elastomer-based sealants.

When polyisobutylene is added to Clear Sealants it imparts outstanding peel adhesion and good aging characteristics.

Stretch / Cling Wrap

Polybutene offers excellent cling properties to the film when added to LLDPE.

Polybutene can be added to the production of LLDPE film either by way of

»  LLDPE / PIB masterbatches or

»  Direct addition to the LLDPE during the film extrusion process

The major areas of application for tackified LLDPE are pallet stretch wrap and bale silage wrap.

The films made by incorporating polybutene exhibit good clarity, durability and cling properties.

Lubricants

KVIS 30 finds its application in PIBSA-Polyisobutylene Succinic Anhydride as a dispersant and performance package in lubricant segment.
