Pearlbond™ 702 EXP

Generic Family: Thermoplastic Polyurethane Elastomer (Polyester) • Supplied by: Lubrizol Advanced Materials, Inc.
Type: Pearlbond™ 702 EXP is linear, polyester-based polyurethane, supplied in form of small beige granules, which combines an extremely fast crystallization rate with an extremely high thermoplasticity level. It is used for Hot Melt Adhesives.

Uses: Powder, hot melt adhesive, film

APPLICATIONS
Pearlbond™ 702 EXP can be used for making heat-sealable fabrics (thermobonding films, webs…), obtained by coating processes such as:
  • Hot Melt Coating system: Rotogravure hot melt printing. The product is melted in an extruder and then pumped into a deposit in front of the engraved roller.
  • Powder Coating system: Scattering or dot-coating (powder or paste). The product is previously ground into powder, by cryogenic grinding. The particle size of the powder will depend on the application technique to be used.
Pearlbond™ 702 EXP is suitable for use in extrusion and powder applications where the following features are of high value to the customer: high speed process at low viscosity and high bonding strength in minutes, among superb wettability.
It can also be combined with more rigid resins or reactive systems to increase the flexibility and elastomeric behaviour (compounds) decreasing their Tg.
