What is Lantor Soric?

Lantor Soric is an advanced flow media and core material designed primarily for resin infusion manufacturing processes.

Its unique honeycomb-like structure promotes resin distribution throughout the laminate while simultaneously acting as a lightweight core. This allows manufacturers to reduce production time while achieving excellent stiffness-to-weight ratios.

Key Benefits of Lantor Soric

  • Optimised resin flow during infusion
  • Increased panel stiffness
  • Reduced component weight
  • High compression strength
  • Improved surface finish quality
  • Faster production cycles

Typical Applications

  • Boat hulls and decks
  • Marine interiors
  • Vehicle body panels
  • Motorhomes and caravans
  • Railway components
  • Industrial composite structures

What is lantor coremat?

Lantor Coremat is a non-woven polyester core material designed to create controlled laminate thickness while reducing weight and resin consumption.

Unlike Soric, Coremat is particularly valued for its versatility across different manufacturing techniques, including hand lay-up, spray-up, and vacuum infusion.

Key Benefits of Lantor Coremat

  • Consistent laminate thickness
  • Easy handling during lay-up
  • Compatible with multiple manufacturing methods
  • Improved dimensional stability
  • Good impact resistance
  • Cost-effective solution for large parts

Typical Applications

Coremat is frequently used in:

  • GRP mouldings
  • Marine components
  • Building products
  • Sanitary ware
  • Transport applications
  • Industrial panels

Soric vs Coremat: Understanding the Key Differences

1. Resin Flow Performance

One of the biggest differences between the two materials lies in resin distribution.

Soric was specifically developed to improve resin flow during vacuum infusion. Its internal structure creates channels that allow resin to travel quickly and evenly throughout the laminate.

Coremat can also be used in infusion processes but does not provide the same level of flow optimisation.

Winner: Lantor Soric

2. Weight Reduction

For manufacturers focused on lightweight structures, Soric generally offers better weight savings.

Its cellular structure creates stiffness without significantly increasing component weight, making it attractive for marine and automotive applications where reducing weight can improve performance and efficiency.

Winner: Lantor Soric

3. Thickness Control

Coremat excels when precise laminate thickness is required.

Because it provides highly consistent thickness throughout the part, it is often preferred in applications where dimensional accuracy is critical.

Winner: Lantor Coremat

4. Manufacturing Flexibility

If your workshop regularly uses hand lay-up or spray-up techniques, Coremat is often the more practical solution.

Soric performs exceptionally well in infusion manufacturing but may not offer the same flexibility across different production methods.

Winner: Lantor Coremat

5. Structural Performance

When the goal is to maximise stiffness with minimal weight increase, Soric generally outperforms Coremat.

This makes it especially popular in high-performance marine and transport applications.

Winner: Lantor Soric
