Our product portfolio is divided into two macro categories: technopolymers on the one hand and commodities on the other.
Technopolymers
Bio Polymer – Compostable Thermoplastic PLA based Compound
Application: coffee, infusions and solubles compostable capsules
TECHNOPOLYMER loaded with 20% natural glass fiber – HB (flammable). Features: non-hygroscopic, good dimensional stability. PBT can be HB or V0 without other intermediate self-extinguishing grades.
Application: electrical sector (internal parts of electric capacitors, plugs for winding capacitors, where self-extinguishing is not required, cases with V0 Self-extinguishing)
PBT with:
20% glass fibre;
Self-est. UL 94 V0 certificate;
High density due to the presence of Antimony trioxide (a mineral) in the self-extinguishing halogen package in addition to the glass fiber.
Features :
– Gloss;
– Can be chrome/ painted;
– Enriched with f.v.;
– No high chemical resistance;
– Flammable HB UL94;
– Highly flammable, from grades HB directly to grades V0, which due to the high content of self-extinguishing substances lose the mechanical and aesthetic performances that characterize the basic version.
Application: electrical sector
Self-extinguishing V1 UL94, contains high percentages of PS (BENEFITS in the transformation LOSS in temperature resistance features, lower VICAT and HDT, RTI not certified);
EXCELLENT electrical resistance and dimensional stability
LOW chemical resistance
(Sabic Noryl SE1 grey): low PS percentages (more complex transformation – greater resistance to high temperatures – RTI certified 110°-105°-110°).
Application:
– Electrical sector;
– Degrees for the food sector available;
– Good thermal dissipation;
– Hard parts can be painted;
– It can be added with foaming agents to create a microcellularization;
– Halogens free;
– Incompatible with contact with hydrocarbons.
PP self-extinguishing V0 UL94.
Application: electrical sector
PP V2 – UL V2 Certificate – GWIT and GWFI
Application : electrical sector
PP OMOpolymer 20% grey high fluidity glass fiber.
Used for the electrical sector.
Special ETI product.
High fluidity polypropylene
Medium rigidity
Suitable for use < 0°C
Used for thin thicknesses < 1.3mm
PP self-extinguishing V2:
– contains antimony trioxide;
– UL certified for self-extinguishing V2 and RTI 105°C
– not suitable for UV exposure;
– can be laser marked as it is added with special pulverized mica.
Application:
– Electrical sector;
Self-extinguishing V0 UL94 .
Blend between PC and ABS. Thickness >1.6mm. Used only to produce CAPS in the electrical sector.
Increase in PC percentage corresponds to an increase of HDT > 140°C.
ABS to make it more printable (soft) .
Application: Electrical sector.
Polyamide PA6 25% glass fiber Gray RAL 7033.
Polyamide, also called nylon.
Depending on the polymer, it is divided into Nylon 6,6 obtained from hexamethylenediamine, and Nylon 6 obtained from caprolactam.
PA6 is softer than PA66.
PA6 has longer moulding cycles than PA66.
The PA6 A G5 GR is used in ETI for the electrical sector of capacitors.
H2 for high temperature resistance;
HF halogen free and Ross phosphor free;
Applied in the manufacture of electrical capacitors parts.
V2 to ≠ 1.6;
Formerly used for electrical capacitor enclosures.
Used for plastic fasteners in the electrical sector
Colours : natural/ black
Halogen free and red phosphorus free with GWIT 775° and CTI 600.
Used for the plates moulding for the electrical sector.
[PA 66 G5 V0 Alo free] = PA66 V0 25% halogen free and red phosphorus free glass fibre with GWIT 775° and CTI 600.
Employed in the electrical sector
Not loaded;
Halogen free;
Application: electrical sector.
Commodities
Low-density polyethylene.
Application: wine caps production. Grades used MFI 3.5/10
Used in the packaging industry to achieve an excellent barrier to oxygen and steam, making the product very competitive. Thanks to this polymer external flow packs can be avoided.
PP with additives: depending on the technical requirements of the product talc, carbon or glass fibre fillers can be inserted.
High rigidity homopolymer polypropylene (high elastic modulus).
Applications:
– electrical sector;
– food sector.
PP talc filled 27%
It has a high bending modulus and a high HDT. Used in the electrical sector. The products made with this material are more repellent to adhesion than the normal PP as well, with good sliding surface.
Application:
household appliances: washing machine and dishwasher detergent trays.
Medium fluidity polypropylene;
Medium rigidity;
Suitable for use up to -20°C;
Used for products with thickness >1,3mm
Polypropylene is divided into 3 groups:
– OMOpolymer (PP H): symmetrically ordered molecular structure;
– Copolymer (PP C): formed by ALTERNATING blocks of propylene and ethylene;
– Random copolymer (PP R): formed by RANDOM blocks of molecules of Propylene and ethylene.
– All PP can be added at the origin with antistatic agents to prevent the attraction of dust and with nucleants to speed up crystallization during cooling phase;
– In general, as the length of the PP chain decreases, fluidity and fragility increase proportionally;
– The evolution of industrial processes over time has led to having PP with doubled short chain and fluidity than 20 years ago, maintaining elasticity and resilience of previous;
– OMOpolymers may have a higher modulus of bending than COpolymers. Some special ones can be reinforced with a mineral filler (10-15%), they are better resistant to high temperatures (HDT higher than 10-12 °C compared to PP C), but not recommended for use at temperatures below 0 °C .
RANDOM PP (PP R) have a high transparency, are very elastic and do not whiten along the bending lines, resist to high working temperatures from 0 to 70°C .
