Intumescent Flame Retardant for PP (Pellets, 30%)

admin — Thu, 08 Feb 2018 13:49:26 +0000

Description

An amino-phosphate intumescent system — a non-toxic halogen-free flame retardant for polypropylene of any type (homopolymers, block copolymers, injection molding PP produced by Ziegler-Natta and metallocene technologies). When heated, it forms a foamed carbonized layer that isolates the polymer from oxygen and flame.

Key parameters

Flame retardancy: UL94 V0 at 1.6 mm specimen thickness
Dosage: 30% by weight of the PP compound
Supply form: pellets (ready for feeding into a twin-screw extruder)
Halogen-free: no bromine or chlorine, no HBr/HCl on combustion
Compatibility: injection molding PP, block copolymers, homopolymers
PP synthesis technologies: Ziegler-Natta and metallocene

Applications

Electrical engineering. Socket housings, connectors, lamp holders.

Construction materials. Honeycomb panels, insulation elements.

Furniture industry. Housings, fasteners, connectors.

Automotive. Interior panels, air ducts.

Household appliances. Appliance housings, heating units.

Description

Exaflame PA/PBT is a non-toxic, halogen-free flame retardant based on metal salts for polyamides (PA6, PA66, PA12) and polyesters (PBT, PET). This bromine-free and chlorine-free system with low smoke emission provides UL94 V0 and 5VA ratings at moderate loadings while preserving the mechanical properties of the matrix. It releases no corrosive acid gases during combustion — critical for electronic applications. An alternative to Clariant Exolit OP 1230/1240/1311 (DEPAL) in halogen-free FR applications for PA66 GF.

Key properties

UL94 V0 + 5VA for PA, PBT, PA66 GF — outstanding efficiency
Halogen-free — compliant with RoHS, REACH and EU directives on brominated substances
Preserves the strength and HDT of reinforced PA66 GF / PBT GF compounds
Low smoke emission, non-toxic combustion products
No corrosive HBr/HCl gases — for electronics and cable insulation
Compatible with PA6, PA66, PA46, PA12, PBT, PA66 GF30, PBT GF30

Applications

Electrical engineering and electronics. Socket housings, relays, cable ties, contactor housings — UL94 V0/5VA without halogens.

Automotive (e-mobility). Battery module housings, high-voltage connectors, EV cable connections — meeting UL94 V0 + glow wire test requirements.

Cable insulation and jackets. PA66/PBT for jackets with zero HBr/HCl emission in case of fire (tunnels, subways, data centers).

Rail transport. EN 45545-2 R22/R23 (HL2/HL3) — interior components, housings.

Household appliances. Housings for heating appliances, coffee machines and irons — per IEC 60335 and UL94.

Flame Retardant for Polycarbonate and PC/ABS

admin — Thu, 08 Feb 2018 13:41:50 +0000

Description

Exaflame PC is a non-toxic flame retardant based on metal sulfonate salts for polycarbonate (PC) and polycarbonate/ABS blends (PC/ABS). A halogen-free system — no bromine or chlorine, with low smoke emission and zero toxicity of combustion products. Provides UL94 5VA and V0 ratings at loadings below 0.3% — the highest efficiency on the market for PC. It does not alter the transparency or mechanical properties of the matrix. An alternative to Cabot KSS and 3M FR-2025 in transparent and translucent PC applications.

Key properties

UL94 5VA + V0 at <0.3% loading — outstanding efficiency
Halogen-free system — compliant with RoHS, REACH
Low smoke emission, non-toxic combustion products
Preserves PC transparency — suitable for transparent components
Does not affect the impact strength or HDT of the matrix
Compatible with PC, PC/ABS, PC/PBT, PC/PET

Applications

Electrical engineering and electronics. Housings for sockets, switches and distribution boards, LED luminaire housings — requiring UL94 V0/5VA.

Aviation and rail transport. EN 45545-2 R22/R23 (Hazard Level HL2/HL3) — interior panels, insulation.

Transparent protective elements. Helmets, safety glasses, transparent guards for electrical equipment — where flame retardancy plus transparency is required.

Building materials. Polycarbonate multiwall glazing, greenhouses, roofing panels with fire-safety requirements.

Automotive. Mirrors, headlamps, electronic unit housings — per FMVSS 302 and OEM specifications.
