Flame-retardant (unfilled) grades. These use a nonbrominated, nonchlori-
nated flame retardant, allowing for ECO-label compliance. They offer a
range of thermal and mechanical properties and cost economy for appli-
cations including computers and business equipment, electrical, electronic,
construction, telecommunications, and appliances. Representative prop-
erties of flame-retardant PPE/PS grades appear in Table 9.3. Flame-retar-
dant grades and key features include

Noryl N190X: 190°F (79°C) HDT at 264 psi (1.82 MPa); UL-94 V-0/5VA
ratings
Noryl N225X: 211°F (99°C) HDT at 264 psi (1.82 MPa); UL-94 V-0/5VA
ratings
Noryl N300X: 293°F (145°C) HDT at 264 psi (1.82 MPa); UL-94 V-0
rating
Noryl SE100X: 199°F (93°C) HDT at 264 psi (1.82 MPa); UL-94 V-0/V-
1 ratings
Noryl SE1X: 244°F (118°C) HDT at 264 psi (1.82 MPa); UL-94 V-0/V-
1 ratings

Reinforced flame-retardant grades. These offer a broad range of fillers
such as fiberglass, mineral, and other exclusive technologies, which pro-
vide increased levels of strength, stiffness modulus, dimensional stability,
and electrical conductivity. In addition, these reinforced resin grades use
a nonbrominated, nonchlorinated flame retardant, allowing for ECO-label
compliance. These materials are generally useful to replace metal assem-
blies and consolidate parts. Applications include uses in computer chas-
sis, pen bodies, paper path applications, electronic media carriers, lighting
ballasts, timers, switches, and appliance parts. Representative proper-
ties of reinforced, flame-retardant PPE/PS grades appear in Table 9.4. FR
reinforced grades and key features include.
