Choosing the right bristle type is critical in brush making. Boar bristle (~0.20mm diameter), known for superior strength and elasticity, is ideal for high-end applications like oil painting, shaving, and industrial brushes. Pig bristle (~0.15-0.16mm), softer and more flexible, suits standard painting brushes.

Visual & Structural Features:

• Boar: Generally dark, tough, single follicle, long bristles (up to 10 cm).

• Pig: White or pale, shorter (2-5cm), flexible, compound follicle structure.

Performance:

• Boar: Strong, durable, resistant to bending, moderate moisture absorption.

• Pig: Softer, less durable, higher moisture absorption and deformation.

Typical Uses:

• Boar: Premium painting brushes, shaving, climbing brushes, friction and filtration products.

• Pig: Standard and economical paintbrushes.

Pricing & Demand:

Boar bristle is costlier due to premium quality and demand. Pig bristle is affordable and widely available.

Origin:

Boar bristle sourced from wild/farmed boars (Europe, Asia), while pig bristle is a byproduct of pork industry processing.
