THE PROBLEM

Core material costs are eating your laminate budget

We offer stocked inventory, global sourcing, and made-to-order solutions to meet your timeline and specifications.

Brand-name cores keep climbing in price

Supply is
unpredictable

Switching
feels risky

Imsent cores are engineered as direct equivalents to the Soric grades you already run, so you keep your process and drop your cost per part. Here is the lineup.

WHY IMSENT COMPOSITES

Brand-name performance. Production-friendly pricing.

IMSENT offers a comprehensive portfolio of fibers and auxiliaries used in lightweight structures, reinforcement, and insulation.

Lower cost
per part

Brand-equivalent performance without the brand-name markup, so every hull, blade cover, or panel costs less to produce.

Keep your existing process

Direct alternatives to Soric grades, matched by application and thickness to help simplify validation and reduce the need for major changes to your existing layup and infusion process.

Fewer materials in your stack

Core and resin flow medium in one product. That removes a consumable from your bill of materials and a step from every layup.

Supply you can schedule around

US and Canadian warehouses keep material close to your shop, with quotes available to help you plan.

THE PRODUCT LINE

Four cores. Four different jobs.

We offer stocked inventory, global sourcing, and made-to-order solutions to meet your timeline and specifications.

Alternative to Soric® XF

PM Core

THE INFUSION WORKHORSE

A cost-effective core and infusion medium for closed-mold parts such as hulls, decks, transportation panels, tanks, nacelle covers and other large infused structures. PM offers the broadest standard thickness range in the product line, with built-in flow channels that can eliminate the need for separate flow media.

Thicknesses : 1.5, 2, 3, 4, 5, 6 mm
Weight : 125–350 g/m²
Resin uptake : 0.4–0.5 kg/m² per mm
Best for : Hulls, decks, large infused panels

Alternative to Soric® SF

PS Core

THE RIGIDITY BUILDER

A standard-flow core for adding rigidity to hull sides, decks, hatches, and consoles without piling on glass. PS maintains less than 8% thickness loss under vacuum and has a resin uptake of 0.4–0.6 kg/m²/mm. It delivers 4 MPa compressive strength, providing added laminate rigidity with predictable resin consumption.

Thicknesses : 2, 3 mm
Resin uptake : 0.4–0.6 kg/m²/mm
Compression strength : 4 MPa (ISO 844)
Best for : Hull sides, hatches, consoles, small craft

Alternative to Soric® TF

PT Core

THE THIN CONFORMABLE CORE

A lightweight, conformable infusion core for closed-mold components where low thickness and surface appearance are important. This core can help to prevent fabric weave print through.

Thicknesses :1.5, 2 and 3 mm
Temperature rating : Up to 180°C
Resin uptake : 0.4–0.6 kg/m²/mm
Compression strength : 4 MPa (ISO 844)
Best for : Gelcoat topsides, cosmetic surfaces

Alternative to Soric® LRC

PX Core

The lightweight

The low-resin-consumption core for weight-critical builds. With the lowest impregnated density in the line and 5 MPa compressive strength, PX absorbs less resin per square meter, which can mean lighter laminates, lower resin costs, and improved performance in weight-sensitive marine, drone, transit, and industrial parts.

Thicknesses : 1.5, 2, 3 mm
Density : 400–500 kg/m³ (lowest in line)
Resin uptake: 0.3–0.4 kg/m²/mm
Compressive / shear : 5 MPa / 30 MPa
Best for : Weight-critical hulls, tenders, panels

Questions Builders Ask

Frequently asked questions

How do these products compare with Lantor Soric® grades?

They are offered as alternatives to corresponding Soric® grades and nominal thicknesses: PM to XF, PS to SF, PT to TF, and PX to LRC. We recommend reviewing the TDS and validating samples in your own resin system, laminate, and infusion process before production use.

Can I use these cores for boat hulls and decks?

Yes. The product line is suitable for closed-mold marine applications including hulls, decks, and other boat and yacht structures. The cores are compatible with unsaturated polyester, vinyl ester, phenolic, and epoxy resins. For cosmetic surfaces, PT’s thin and conformable construction may help reduce fabric print-through, depending on the laminate and process.

Do I still need a separate flow medium in my stack?

The cores include built-in 0.5 mm flow channels and are designed to function as both core material and resin-distribution medium. Depending on the part geometry, laminate, resin viscosity, and infusion strategy, this may reduce or eliminate the need for separate flow media. Process validation is recommended.

What resins are these compatible with?

The cores are listed as compatible with unsaturated polyester, vinyl ester, phenolic, and epoxy resins. Maximum processing temperature depends on the grade: 170°C for PS, 175°C for PM, and 180°C for PT and PX. Customers should confirm suitability for their specific resin, cure cycle, and laminate.

What are your minimum order quantities and lead times?

Minimum order quantities and lead times depend on the grade, thickness, quantity, and current inventory. Send us your required product, thickness, and estimated volume, and we will confirm availability and pricing.

Can I get a sample before committing to a production order?

Samples may be available for material and process evaluation. Tell us the grade, thickness, resin system, and intended application, and we will confirm sample availability.
