## Description

This MCP server provides specialized tools for polymer compounding engineers to determine precise additive concentrations and batch quantities. It handles complex calculations including PHR (Parts per Hundred Resin) to mass conversions, weight percentage concentrations, masterbatch dilution requirements, and scaling theoretical formulations to specific target batch sizes. Use `calculate_phr_to_mass` to find additive weights, `calculate_masterbatch_requirement` to account for carrier resin dilution, and `scale_batch_size` to prepare production quantities.

## Tools

### calculate_concentration
Determines the weight percentage of an additive in the final formulation

### calculate_phr_to_mass
Converts relative additive amounts (PHR) into specific mass values for a given resin quantity

### calculate_masterbatch_requirement
Calculates the necessary mass of a masterbatch to achieve a specific PHR of a pure additive

### scale_batch_size
Calculates the required mass of all components to reach a specific target finished product weight

## Prompt Examples

**Prompt:** 
```
I have 500kg of base resin and I need to add an additive at 5 PHR. How much additive do I need?
```

**Response:** 
```
You need 25kg of the additive.
```

**Prompt:** 
```
Calculate the masterbatch needed for 100kg of resin with a target of 2 PHR of an additive that is supplied in a 20% concentration masterbatch.
```

**Response:** 
```
You need 10kg of the masterbatch.
```

**Prompt:** 
```
Scale a formulation to a 1000kg total batch. The additives are: UV Stabilizer at 2 PHR and Carbon Black at 3 PHR.
```

**Response:** 
```
For a 1000kg batch, you need 952.38kg of base resin, 19.05kg of UV Stabilizer, and 28.57kg of Carbon Black.
```

## Frequently Asked Questions

**What is PHR?**
PHR stands for Parts per Hundred Resin. It is the standard unit in polymer compounding used to express the mass of an additive relative to 100 units of the base polymer mass.

**How does the masterbatch calculation work?**
The `calculate_masterbatch_requirement` tool calculates the total mass of masterbatch needed by first determining the required pure additive mass via PHR and then dividing by the masterbatch's active concentration.

**Can I scale a formulation for a specific production run?**
Yes, use the `scale_batch_size` tool. You provide the target total mass and a list of additives with their PHR values to get the exact mass for every component.
