Choosing the correct raw material for paint brush bristles largely depends on the type of paint you will be using and the kind of surface you will be painting. Here's a more detailed guide to help you decide:

1. **Natural Bristle Brushes (usually hog or boar hair)**: Natural bristles are hollow and can easily absorb oil-based paints, varnishes, and other oil-based finishes, resulting in a smooth, even application. The bristles' natural flagging (split ends) helps in evenly distributing the paint. However, they aren't recommended for water-based paint (like latex), as water can cause the bristles to swell and become limp.

2. **Synthetic Bristle Brushes (usually nylon, polyester, or a blend of both)**: These brushes are great for water-based paints (like latex or acrylics), as the bristles don't absorb water and maintain their shape well.

   - **Nylon**: These bristles are soft, flexible, and durable. They work well in all climates and are suitable for both oil and water-based paints. However, they may begin to lose their stiffness in hot weather or after prolonged use.

   - **Polyester**: Polyester bristles retain their stiffness in all conditions, making them suitable for rough surfaces, textured materials, and heavier paints. They can be used with both oil-based and water-based paints.

   - **Nylon/Polyester Blend**: These brushes combine the strengths of both materials and are versatile enough for all types of paint and finishes.

3. **Brush Quality**: Higher quality brushes will have more bristles packed tightly together. This leads to a better paint pick-up and release, which results in a smoother finish. A higher-quality brush will also last longer if it's properly maintained.

In conclusion, synthetic bristle brushes are more versatile and can be used with all types of paint, while natural bristle brushes are preferred for oil-based paints. When choosing a brush, consider the type of paint you're using, the surface you're painting, and the conditions under which you'll be painting.
