Q

PBT Chemical Resistance Boundary

A

PBT's selective chemical resistance boundary lies in halogenated hydrocarbons and strong acids and alkalis; medium list review is a required course for material selection; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Material Analysis PBT; chemical resistance; halogenated hydrocarbon; strong acid and alkali; medium

Q

PBT Home Appliance Application

A

PBT home appliance application is a multi-objective balance of appearance, flame retardancy, heat resistance, and warpage; dedicated grade combinations solve it; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Material Analysis PBT; home appliance; spray-free; flame retardant; heat resistance

Q

PBT Floating Fiber Material Countermeasures

A

The radical cure for floating fiber lies in interface chemistry; compatibilizers and surface-treated glass fiber are the two keys on the material side; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Material Analysis PBT; floating fiber; compatibilizer; SOG; surface treatment

Q

PBT Floating Fiber Causes

A

Floating fiber is the superposition of three factors: compatibility, viscosity difference, and shear; combining process adjustment with compatibilizer works best; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Material Analysis PBT; floating fiber; compatibility; viscosity difference; shear

Q

PBT Anti-Warpage Material Solution

A

Anti-warpage formulation is a mature technical route for glass fiber PBT; mineral symmetrization and amorphous crystallization reduction work together; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Material Analysis PBT; anti-warpage; mineral filler; amorphous; compatibilizer

Q

PBT Thin-Wall High-Flow Demand

A

The preferred flow solution for PBT thin-walling is CBT-type modification; reducing molecular weight is the worst option, functional additives are the best option; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Material Analysis PBT; thin wall; high flow; CBT; low molecular weight

Q

PBT Toughening Modification Route

A

PBT toughening is a trade-off between fluidity and toughness; reactive compatibilization technology is the mainstream route to take both into account; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Material Analysis PBT; toughening; POE-g-GMA; fluidity; blending

Q

PBAT poor filler compatibility

A

PBAT filler compatibility is the core of modification technology; coupling agent modification is the standard method; the 15% upper limit is the performance guarantee line.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Material Analysis PBAT; filler; compatibility; coupling agent; dispersion; 15%

Q

PBAT excessive cost

A

PBAT cost is the main obstacle to industrialization; high filling of filler and thinning are effective paths; multi-layer structure is the technical cost-reduction direction.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Material Analysis PBAT; cost; high; filler; thinning; multi-layer

Q

PBAT low strength

A

Blending modification is the main path for PBAT strength improvement; PLA blending is the industry standard solution; multi-layer structure balances performance and cost.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Material Analysis PBAT; strength; low; PLA; chain extender; blending
