Kynar Flex PVDF fluoropolymers products
Arkema Inc. and Polymer Engineering Company Ltd. to blend Kynar Flex® PVDF with rubber
Arkema Inc. and Polymer Engineering Company Ltd. have developed the capability to blend high performance Kynar Flex® PVDF with various types of rubber. The combination of a thermoplastic fluoropolymer with rubber materials allows melt processing through chemical compatibilization and vulcanization. The capability to create various fluoropolymer and rubber combinations results in products that have a range of properties provided by each respective component.

Kynar Flex PVDF fluoropolymers impart high chemical resistance, resistance to swelling, UV resistance, high heat stability, high contact angle and good release properties. Rubbers can impart a range of other favorable properties such as impact strength, flexibility, strain recovery, electrical resistance, lightweight, softness and compressibility. The final combination of properties can be tailored by the selection of the base fluoropolymer and the rubber, or combinations of rubbers, which will determine overall cost and performance.

These blends of Kynar Flex PVDF and rubber can be extruded into profiles and/or injection and compression molded at temperatures similar to polyolefin thermoplastics.

“Many industries, such as the fuel and chemicals sectors, are challenged by changes that occur related to regulation modifications and technology-related upgrades,” said Marek Gnatowski Ph.D., president, Polymer Engineering Company. “Materials of construction that may have been previously considered reliable for long-term service in 2015 are then determined to be no longer suitable as the contact chemicals are altered for future use. The ability to blend rubber with a high performance fluoropolymer allows the system designer to keep the friendly properties of rubber without early cracking or swelling failures in service.”

Arkema Inc. and Polymer Engineering Company can provide manufacturing guidance for processors interested in offering blends of Kynar Flex PVDF and rubber in applications such as tubing, hose, gaskets, O-rings, films, linings, wire insulation, cable jacketing and molded structural parts. Due to the lower melting point associated with PVDF, compared to other fluoropolymer materials, these blends can be processed on standard equipment with minimal or no additional investment.

Mach1 UHMPE sheet from iPoly
Mach1 ultra-high molecular weight polyethylene (UHMPE) from iPoly Inc. combines wear, low friction, corrosion resistance and impact strength in a cost-effective sheet. It retains key physical properties in sub-zero temperatures and is chemical resistant. Mach1 is a high-impact, low coefficient of friction polymer that mimics many of the characteristics of PTFE. Applications for Mach1 include food grade components, wear parts, sliding parts, conveyor system parts, paddles, slides, guides, machined wear components, etc. It is suitable for applications that require sliding action with as little resistance as possible and an extended service life to withstand abrasion and wear.
FOME-COR collection for displays, graphic arts, framing
FOME-COR® collection for displays, graphic arts, framing
3A Composites USA, Inc. announced its integrated FOME-COR® Collection, a portfolio of foam boards designed to meet the needs of the display, graphic arts and framing industries. Introduction of this collection follows the company’s acquisition of the EnCore® Products and Elmer’s® foam boards division from Newell Brands, Inc.

“3A Composites is focused on providing the most expansive and forward-thinking line of high-quality rigid substrates available to meet the evolving needs of the display, graphic arts and framing markets,” said Chuck Kunze, director, product management and marketing, 3A Composites USA, Inc. “The newly integrated FOME-COR Collection strengthens our offering to these industries and solidifies our commitment to the framing and retail markets. This collection combines technology from both 3A Composites and EnCore, ensuring that our foam boards offer unparalleled cutting and recovery performance in the market. Our new product portfolio — represented by the seven sub-brands comprising the FOME-COR Collection — is just the first major change in our full product lineup that will continue to expand in 2021. Stay tuned in the coming months for more innovative brands and product introductions from 3A Composites USA.”

The newly integrated FOME-COR Collection offers a variety of products with premium bright-white, double clay-coated facers that are suitable for screen printing and direct digital printing applications as well as products with high-quality uncoated facers that provide flat, smooth surfaces for mounting graphics or backing photographs and fine art in framing applications. All FOME-COR products are produced using a proprietary manufacturing process that creates a foam core conducive to cutting and fabrication and which delivers superior performance in both pillowing and memory/recovery variations. The FOME-COR Collection includes:

FOME-COR is comprised of polystyrene foam with bright-white coated paper facers or black uncoated paper facers, a composition that is lightweight and easily cut even by hand. FOME-COR is suitable for screen printing and direct digital printing applications. It is also appropriate for die-cutting with a compressed, pillowed edge that stays closed. FOME-COR is embossable to create 3-D effects in displays.

New FOME-COR WITH ENCORE TECHNOLOGY is comprised of specially formulated memory foam with bright-white coated paper facers or black uncoated paper facers. This composition offers a surface that is more resilient to dents and allows edges to remain open in die-cutting applications. Bright-white coated facers provide excellent printing results.

New FOME-COR FOUNDATION is comprised of extruded polystyrene foam with a variety of high-quality acid-free facers. This rigid backer provides a flat, smooth surface for superior mounting and framing with no read-through lines. FOME-COR FOUNDATION is suitable for the archival preservation of valuable art and photographs; antique white paper facers meet Library of Congress standards for conservation framing. FOME-COR FOUNDATION cuts with the same quality of standard FOME-COR and offers a cost-effective alternative to corrugated cardboard for non-printing applications.

New FOME-COR SINGLESTEP® is comprised of extruded polystyrene foam with coated facers, one side with heat-activated adhesive that activates with low temperature settings to achieve a quick and damage-free mount. FOME-COR SINGLESTEP eliminates the need for hot melt tissue stock in the mounting process and can be used with heated mechanical or vacuum dry mount presses or with a heated roller laminator. Reusable release papers are included.

New FOME-COR QUICKSTIK is comprised of extruded polystyrene foam with coated paper facers, one side covered with either low-tack or high-tack pressure-sensitive adhesive that eliminates the need for pressure-sensitive adhesive stock. Release paper peels back to reveal adhesive for fast and easy mounting. Repositionable low-tack board is suitable for hand-mounting applications while permanent-bonding high-tack board is pressure-activated and appropriate for high-volume automated mounting applications.

FOME-COR JETMOUNT is comprised of enhanced densely extruded polystyrene foam with bright-white coated or black uncoated paper facers. This denser foam core provides increased rigidity and warp resistance making it suitable for more demanding mounting jobs such as free-standing displays, signage and framing. FOME-COR JETMOUNT cuts with the same quality as standard FOME-COR.

FOME-COR CANVAS is comprised of polystyrene foam with embossed “canvas-like” coated paper facers on both sides. This deeply embossed texture creates an artistic look while offering an economical alternative to competitive canvas-like products. FOME-COR CANVAS cuts with the same quality as standard FOME-COR.
